It's summer in Moose Junction, and twelve-year-old Abby McCourt should be excited about the approaching solar eclipse--especially because she's obsessed with astronomy--but she's not. After the incident at the Memorial Day barbecue, nothing has been the same. Her friends avoid her. Her parents are stressed. And the one person she felt closest to--her older sister Blair--has been sent to a treament facility to learn how to eat again. But wait . . . rewind a bit. This didn't really start with Blair's meltdown over a cupcake at the barbecue. When Abby thinks on it, she can see traces of her sister's eating disorder from years back.
