A couple of reviewers think that you'll find it in When Mike Kissed Emma. I couldn't be happier with the reviews I found online this weekend.
My favorite lines from them?
Becky at Becky's Book Reviews had this to say:
I know I would have really really loved this one if I'd read it as a young teen.
And Lauren at Lauren's Crammed Bookshelf said this:
The plot was fun and fast paced leaving me to be constantly turning the pages, curious to see what would happen next.
Please go to both of these sites and read the full reviews!
