In January I will be teaching Directed Reading at the Whidbey Island MFA. Last year I taught crossovers YA<-->Adult, but my students got very depressed. So, I decided to teach funny YAs next.
John Green's writing is always excellent, and The Fault in Our Stars has some funny scenes. Still, both main characters have cancer and their situation made me cry.
I've read Flip by Martyn Bedford and Au Revoir, Crazy European Chick by Joe Schreiber. I have ten others in my list. However, if you have written a funny YA, please, let me know.
