If you read the first book, none of this should be a spoiler, but if you haven't, then proceed with caution.
Let me get my one gripe out of the way first. Paris is pretty. Like, really super duper fantabuloso everyone-with-eyes-wants-to-bang-him sexy hot. I know this because the author reminds the reader of this repeatedly. If I cut and paste all those passages together, it would probably take up five pages minimum. I vaguely remember being annoyed by this in the first book, but in this book, we're told that Paris's tiger virus has reached critical, that he's lost 50 pounds and is only 150-something, pale, always cold - he's sick, chronically so. So I don't need to hear about how super duper mega hot sex-on-legs he is every other page. One, I actually remember that from the previous book. Two, he's SICK! And at over six feet and only 150 pounds, he's not broad-chested. He's a toothpick. I just found the constant fascination with his sex appeal to be really shallow and misplaced in this book, and I could've done without it. Especially since the author could've gotten the same point across by showing and not telling...and telling...and telling...and telling...
Moving on to the actual story:
On the mystery front, I give this one three stars. The mystery wasn't really that involved here, and the revelation of the whodunit comes almost by accident. Almost. And since Roan's in an emotionally unstable place, that outcome isn't what you'd expect it to be - and that's all I'm saying about that.
On the personal story front, I give this five stars. Read this with a box of tissues close at hand, because you're going to need it! In only two books, or two and a half if you read the novella "Infected: Paris" before this one, Ms. Speed created a beautiful couple in Roan and Paris. They're flawed, they're sometimes stupid, they're occasionally too sweet to bare, and they're real. And in this book, they're raw. They both know what's coming, and while Paris is preparing for the inevitable, Roan's living as close to denial as he can get for as long as he can, because to face reality would be the end for him as well. The supporting cast is all back. Dee is a saint of an ex-boyfriend, and Kevin's still a mess. Matt's much more prominent here. We don't see as much of the coppers, but when we do we get to see their concern and support.
There are a couple of things that are brought up and then dropped, and some things are mentioned that happened between books that I would've liked to see on page. The editing is better than the first book but could still use work on making the "he's" and "his" more clear on who is being talked about. Still, the editing here is better than many.
