Gender Blender by Blake Nelson was an absolutely amazing book. It is sort of like the movie Freaky Friday, but instead it's a boy and girl in 6th grade. Many interesting things happen to each of them while they are in each others bodies. Tom gets his period and Emma has to keep her best friend from kissing her. Both Emma and Tom must learn to cooperate again, or they may never go back to their own bodies. This book was so unlike anything I'd ever read, that I read it twice and Im considering buying it! If you loved Freaky Friday, check out this book for a new and exciting twist.
