So, I picked this one up on something of a lark. Not that I don't like the author's work or anything, because I do. I just wasn't really looking for this at the time I saw it, and it was an "aw, what the hell, why not" buy, sort of like impulse-buying a pack of gum or candybar at the check-out counter because it's in your face at the time. 
 This was quite the entertaining read. I didn't have a great idea of where I thought it was going to go, and I put together the wrong clues at first. And there were some red herrings too, which kept me guessing. All of this I enjoyed because I wasn't ever sure how it would play out. But it all worked. And I could definitely see the possibility for other stories in this universe for a couple of the secondary characters, with the ability for these guys to still show up in the story too. 
 So: Murder mystery with serial killer? Check. 
 Post-apocalyptic government-created genetic mutations? Check. Check. 
 Overprotective lovers, owners, and friends? Check. Check. Check. 
 Definitely worth the read.
