Summary
An interplanetary battle is renewed in an epic novel of a warring solar system by the author of Ballistic。
The war should have been over。 But it’s not for a group of nationalists grabbing for control。
It’s been two weeks since a missile with a nuclear warhead tore through the planetary defenses in the most blistering large-scale attack ever committed in the history of the Gaia system。 Commander Dunstan Park of the Rhodian navy has been handpicked to command an experimental cruiser that could dictate the course of the escalating conflict。 All he has to do is keep the ship from falling into the wrong hands。
On Gretia， the powder keg is beyond control。 A terrorist attack against civilians draws Idina Chaudhary into a costly battle。 It also forces a cautious Aden Jansen back into the fray。 Now dedicated to a just cause， he’s still keeping his past hidden。 The risk of exposing his former alliance could twist not only his fate but also that of his sister， Solveig， heir to the family empire。
With no time to waste， Dunstan hits the ground running。 But as insurgents threaten the unstable peace， what’s ahead for both sides could change the destiny of the Gaia system forever。

4。5 Stars Rounded UpI loved this novel and could barely put it down once I started it。 There was never a dull moment and I found if I blinked too fast I missed key moments。 The novel is told from four main characters whose lives rarely interact。 However， they’re still connected as they’re all fighting the same battle。 Aden and his friends/crew find themselves being hunted after the events of the last novel。 After a tragedy （which I did not see coming） they decide to go on the offensive。 These po 4。5 Stars Rounded UpI loved this novel and could barely put it down once I started it。 There was never a dull moment and I found if I blinked too fast I missed key moments。 The novel is told from four main characters whose lives rarely interact。 However， they’re still connected as they’re all fighting the same battle。 Aden and his friends/crew find themselves being hunted after the events of the last novel。 After a tragedy （which I did not see coming） they decide to go on the offensive。 These portions of the novel were sad， I actually shed a few tears。 But I loved the final resolution as I found it was the perfect ending。 He was my second favorite character and I enjoyed these portion of the novels the most as I found the character development and action the best。 Solveig is trying to run one of the most powerful Gretian corporations while maintaining a personal life and trying to develop a romantic one。 Her POV allowed the reader to see what life was like under a more strict lockdown with more stops， checks and military abuse。 However， I also found her parts the slowest as I didn’t really care about the day-go-day paperwork and meetings required to run a corporation。 The ending helped elevate her portions as the action and suspense was intense。 The conclusion and cliffhanger annoyed me a bit though， no other character had such an annoying cliffhanger。 Dunstan gets a new ship and is tasked with hunting down the rebels。 He agrees to allow Aden to help out。 I loved Dunstan adjusting to life on a new， cramped， ship。 There was a lot of technical speech so these portions were a bit slower。 But I loved the conclusion to the battle， never read a science fiction novel where a battle was so easily won。 Idina is tasked with babysitting duty and gets caught up in numerous battles。 She is by far my favorite characters and I got excited every time a chapter was told from her POV。 She is strong， smart， determined and brave。 Normally I don’t read the acknowledgements at the end of novels but I did this time。 I’m glad I did as Kloos talks about his difficulties writing while dealing with COVID and the American election。 I found it highlight the difficulties authors/artists may have finding creative inspiration and maybe readers should be patient if book releases are delayed （I’ve read some hateful comments online from readers who’ve sworn off series’s due to delayed releases）。 Overall a great science fiction/space opera/military fiction that I would strongly recommend to fans。 I plan to continue the series and am hoping to get book。 4 as an ARC so my wait time is delayed。 Thank you to NetGalley and 47North for the ARC。 。。。more

I have recently completed my read of Marko Kloos' "Citadel，" published by 47 North （who graciously provided me with an ARC for purposes of review）。 Many of you will be aware of the author's prominence in the area of military science fiction， and while I have only a passing familiarity with his canon overall， I am pleased to report that if this text is typical of his work， perhaps I need to take a closer look at his preceding work。 "Citadel" is what is often characterized as a "space opera" by so I have recently completed my read of Marko Kloos' "Citadel，" published by 47 North （who graciously provided me with an ARC for purposes of review）。 Many of you will be aware of the author's prominence in the area of military science fiction， and while I have only a passing familiarity with his canon overall， I am pleased to report that if this text is typical of his work， perhaps I need to take a closer look at his preceding work。 "Citadel" is what is often characterized as a "space opera" by some; the plot is propelled by military events in the many character's recent past as well as the future （by the look of things）。 One of the more interesting features of the text is its narrative structure。 It is told from multiple points of view which eventually converge （more or less） in the readers mind。 The good news is that he actually pulls this off。 As many of you may know， this trick is more easily described than successfully pulled off。 The characters are well drawn， and I as I pointed out， the convergence or "awakening" on the reader's part to their relationships to each other works well to propel the story。 Action is interesting， and as is common in this type of text， the technology is fascinating and （a bonus） relatable to present concerns in military technology。 While it takes a few minutes to get into， it works and works well。 It is well worth the investment of your time。 。。。more

I have been anticipating the release of this book for a year。 The author， Marko Kloos， said that the book was difficult to write in 2020 due to Covid 19 and frequent US political disruptions。 It came out well， however。 Kloos told the story from the perspective of four principal characters developed in the first book of the Palladium Wars series。 Citadel is book three in that series。After losing his former ship in the last book， Commander Dunstan Park is assigned to a new top-secret Rhodian navy I have been anticipating the release of this book for a year。 The author， Marko Kloos， said that the book was difficult to write in 2020 due to Covid 19 and frequent US political disruptions。 It came out well， however。 Kloos told the story from the perspective of four principal characters developed in the first book of the Palladium Wars series。 Citadel is book three in that series。After losing his former ship in the last book， Commander Dunstan Park is assigned to a new top-secret Rhodian navy experimental cruiser equipped with a powerful AI that can quickly hack into， and take over the computer systems of， any ship。 He uses it to go after the unknown Rhodia attackers who blew up one of Rhodia’s cities killing hundreds of thousands of civilians。 He partially accomplishes that。Living under his false identity， Aden and the crew of a merchant ship he’s working on are attacked by an assassin in retribution for the crew turning over a nuclear device they found in their shipment to the authorities。 One of his crew members， Tristan， was killed in the attack。 Grieving the loss of their shipmate and friend， the crew set out to entrap the Gretian nationalists’ members who had anonymously hired them and then taken out a contract on their lives。 They agreed to act as bait to draw the nationalists into a trap that would lead to their arrest by the Rhodesian Navy。 The Navy was able to capture three nationalists’ ships with the fourth getting away。Meanwhile， Idina Chaudhary is on Gretia， protecting the alliances’ occupying force。 The Gretian nationalists attack an armored vehicle that she’s traveling in to protect an alliance dignitary。 That same nationalist group then attacks and destroys the capital city’s police headquarters， almost killing Solveig Ragnar， Aden’s sister。 At the end of this book， a task force of highly trained soldiers is established to root out and destroy the planet’s nationalists’ fighters。 Solveig returns from a successful diplomatic mission for Ragnar Industries and gets a greater amount of freedom from her father’s control。 She can now openly go out with the handsome Gretian police detective introduced in the last book。 Visiting him at the police headquarters canteen for a lunch date， the building is attacked and she is almost killed。 As she recuperates， she learns that her father may have had some part in that attack。 While that disclosure is hinted at， its story will not come out until the next book in this series。 The story in book three， Citadel， is alternately told from the perspective of each of these main characters。 Kloos does a good job of keeping the storyline separate but the story increasingly coalesces around the guerilla war being waged by the Gretian nationalists。 I hope that Kloos can wrap up the series in the next book as I don’t welcome book series that go on indefinitely， like Kloos’ Frontlines series for example。 Markos Kloos is a good military Sci-Fi writer who adds multi-dimension to his characters。 Although they progressing slowly， his stories hold my interest and keep me reading。 Kloos tends to use cliffhangers to assure that readers purchase the next book in a series。 The primary cliffhanger at the end of Citadel is finding out what role the chief industrialist of Gretia has with the Gretian’s nationalist insurgency。 。。。more

Thank you 47North and NetGalley for a copy of the eArc in exchange for an honest review。 This is one of my most anticipated 2021 releases。 While I really enjoy Mark Kloos' more well known series， Frontlines， this series is at a whole new level。 It spans several human-settled worlds in a single solar system。 The first book starts with the release of a POW， Aden， following a postwar imprisonment period。 Aden is a Gretian。 The Gretians lost the war to an alliance of the other planets in the system。 Thank you 47North and NetGalley for a copy of the eArc in exchange for an honest review。 This is one of my most anticipated 2021 releases。 While I really enjoy Mark Kloos' more well known series， Frontlines， this series is at a whole new level。 It spans several human-settled worlds in a single solar system。 The first book starts with the release of a POW， Aden， following a postwar imprisonment period。 Aden is a Gretian。 The Gretians lost the war to an alliance of the other planets in the system。 He skips the conditions of his parole and joins a crew of a courier ship。 This ship gets squashed between an uprising of Gretians against the alliance planets。While Aden is a main focal point， there are three more POVs。 Solveig， Aden's sister， is a vice president of Ragnar Industries， a powerful Gretian corporation。 Idina is a Palladian soldier whose posting is to help keep the peace on Gretia between the occupying government and the Gretians。 Lastly， there is Dunstan， a commander of an alliance warship keeping the peace of the alliance patrolled space。 These POVs are mainly disparate， but start to tenuously come together with brief encounters between some of these characters。The previous two books were fantastic。 This book brings fast paced action and all the feelings。 I cannot wait to hear about Book 4！ 。。。more
