Eleven-year-old Evie is heartbroken when her strict Catholic parents send her pregnant sister away to stay with a distant great-aunt. All Evie wants is for her older sister to come back. But when her parents forbid her to even speak to Cilla, she starts sending letters. Evie writes letters about her family, torn apart and hurting. She writes about her life, empty without Cilla. And she writes about the new girl in school, June, who becomes her friend, and then maybe more than a friend.
As she becomes better friends with June, Evie begins to question her sexual orientation. She can only imagine what might happen if her parents found out who she really is. She could really use some advice from Cilla. But Cilla isn’t writing back.
