Jake, I think, will be a hard character for some to like. On one hand, some will sympathize with him because he was hurt badly years ago and that's why he acts the way he does but on the other hand, he is just a complete fucking douche bag and no matter how much someone hurt you that doesn't give you the right to be an arrogant asshole to everyone else and using your friends. A slut I can understand, an asshole? No way, man. With that said, I think Kelan deserved better than Jake. I felt like if Jake wasn't being a prick, he was crying 'poor me, I got burned by love'. Needless to say, I didn't like him much.
The book opens up to Jake getting a blow-job by a guy he can't even remember the name of (Cary), even though he's hooked up with him multiple times, kicking him out faster than it takes for the sweat to dry. The next night, Jake ditches his friend Tony to go home with Kelan. After just one night (more like half a night, really) Jake knows Kelan is a wolf and kicks him out because he's gotten hurt by a wolf in the past. The next day, Kelan starts his pursuit of Jake. Now it's up to Kelan to persuade Jake what they have is real and getting him to give Kelan a chance to prove it. Add into effect Jake has a stalker bent on harming him, a cat shifter that's in need of some protection and you get a mostly suspenseful story.
I have to admit, the first half of the book wasn't to my liking. Meeting Jake the way we do left a bad taste in my mouth so it took me a while to get invested in the story but eventually Kelan and Jake warmed up to me so by the time all the action starts happening I liked Jake enough to tolerate him. (Although, why he thinks he can just say sorry for all his past douche-bagginess and think that'd be enough to make amends blows my freaking mind.)
With that said, though, I still had some problems with the book. For one, there was still too much sex. At least for me. I've felt this way about the whole series so far, though, so if you've liked the amount of sex in the previous books then you'll have no problems with this one. Also, my questions about Rick and Kelan's feelings still stand.
All in all, I did like a majority of the story. It started off not so good but by the end I was drawn in and invested in it. I think those readers who've liked the series so far with like this one as well.
