I did kind of enjoy reading this book, but there were several things that bothered me:
First of all, the premise seems rather stupid - a rock star (Dagger) who's long known he's gay, but has to hide it, because it would destroy his career. This story seems to take place right now (there are smartphones present) - why would coming out as gay (or even bi, since he also has affairs with female groupies) damage a musician's career? This doesn't seem believable at all... Also, Dagger has lots of one-nighters with (male and female) fans - how could this have remained a secret for so long? It would make sense that at least one of them can't keep from leaking it to the media.
Secondly (spoilerish, but nothing unexpected),
And thirdly (this is a full-blown spoiler),(show spoiler)
Considering also that there were some spelling and grammar mistakes, and the style was a bit clumsy, I simply couldn't give this book more than 2 stars. Still, I guess it's a nice light (and hot ;)) read, if you can suspend your disbelief to simply enjoy the story.
