I only read "Hawkshaw Hunting" by Kelley ArmstrongHawkshaw Hunting 4 starsThis is a Rockton short story （set at some point before the end of the series） with a Nadia Stafford crossover/Easter Egg。 The story didn't add any information about the characters that you didn't know from the series， so you're not missing anything if you skip it， but it was fun seeing Casey and Eric meet Nadia。 You can also easily read this if you haven't read either series and it might whet your appetite for more。 I only read "Hawkshaw Hunting" by Kelley ArmstrongHawkshaw Hunting 4 starsThis is a Rockton short story （set at some point before the end of the series） with a Nadia Stafford crossover/Easter Egg。 The story didn't add any information about the characters that you didn't know from the series， so you're not missing anything if you skip it， but it was fun seeing Casey and Eric meet Nadia。 You can also easily read this if you haven't read either series and it might whet your appetite for more。 。。。more
