Tantalize by Cynthia Leitich Smith
Vampires. Werewolves. Hmmm...that sounds familiar.
Oh, yeah. The ever-popular Twilight series. That's why.
This book was OK. I wanted to know how it was going to end. I was a little surprised as to who the bad guy ended up being....but barely. It was rather predictable.
If you want a vampire/werewolf love triangle type of story, skip this one and go directly to the Twilight series.
