Oh boy， this was one dramatic read！ I've really come to love the variety in Piper and Rayne's Rooftop Crew series--they've been doing a great job with keeping the tropes fresh and the stories are all super different from one another。 Most of all， I absolutely adore their friend group！ I've been eager to read Knox's story for a while since he's been the quiet， mysterious one in the group up until now， and we definitely got to see some depth underneath his uniform。 ;） Part of the fun of this book is that the heroine is a bit of a mystery。。。is it Knox's ex。。。is it someone else？ He's getting a do-over。。。but until you start reading you're not going to know who。 ;） Since I'm trying to keep Knox's love a mystery。。。I'm going to keep this rather brief and say that I loved her！ I loved getting to know her， loved how she and Knox grew closer and fell in love， and I really loved seeing how she fit into their friend group。 Knox's parents were also super precious and I loved them， too。 When it comes to Piper and Rayne's books， I'm always a sucker for the friend groups， and the family moments， and all of those lovely dynamics， and this one did it super well。 Overall， I thought that THE DO-OVER was great！ It was sexy， sweet， and I loved seeing Knox and his mystery lady fall in love！ I was a little bit conflicted going into this one because Knox is a cop， and with everything that's gone on this year I honestly do feel a bit iffy reading romances where the heroes （or even the heroines） are police。 That did kind of damper my excitement for this one， but all in all， I did enjoy it。 A few other little things kept me from absolutely loving this one， namely Dylan's behaviour during parts of it and a tad too much drama for my personal taste， but it was an exciting， fun read and I definitely recommend it to contemporary romance fans who like second-chance stories， especially if you like them to have some twists and turns along the way。 Star Rating: ★★★★ *This review also appears on my blog and other social media accounts。 * Source: I received an egalley to give an honest review/purchased a finished Kindle copy on Amazon CA for my own use。 All opinions are my own。
