"Grow up, Potter!" "No, I don't think I will." Wendy Carter, seventeen years old, is practically all grown up. Because she's been mothering her two younger brothers all their lives, she has been about 30 years old since she was 3. Albeit overprotective and a little insufferable at times, her brothers love her more than anything. James Potter, newly-appointed head boy, never wants to grow up. He loves Hogwarts, and he loves being a teenager. His new position won't stop him from goofing off with his fellow marauders at every chance. The two have never shared anything more than some passing glances and a few classes. However, after James and his infamous friends' Gryffindor "initiation" includes pranking her littlest brother, she decides it's time someone teaches Potter to grow up. She soon learns, though, that Potter also intends on teaching her to act her age in his own way.
