I read this last year, and remember it fondly, although the best part is the beginning, when the plot keeps exploding. Fondly enough to drop ten bucks on the computer game, which I played with the kids on our latest vacation. The game is a cute puzzle and logic type thing, with cut scenes in between covering the plot of the first half of the book.
Here's my dilemma. The game was a gentle PG-13, with a few kisses between the characters and a bit of violence. The book is much racier, with the standard romance sex scenes, including details of oral sex, and an extended sequence where Hari turns into a tiger (although without spikes, I guess). My sixth grader liked the story in the game, and wants to read the book. I've never stopped anyone from reading anything, but I really don't want him to imprint on scenes involving changing species. He's read stuff with sex in them before, but not this explicit and not this close to puberty. (Hi, Wen Spencer's Ukiah series, which taught him to read.)
I'm thinking I'll put a book mark in showing where the game stopped (it only covered the first half, which is the best part anyway) and recommend he stop there. That's where it really starts shifting from action-adventure to spend more time on the True Love part. X trusts that I know what he likes, so he'll probably actually stop there if I tell him it really drags from then on, which I think it would for him. Am I deluding myself? Maybe he'll take one look at the cover and recognize it as a girl book.
