P.S. I miss you

"Evie is heartbroken when her strict Catholic parents send her pregnant older sister, Cilla, away to stay with a distant great-aunt. All Evie wants is for her sister to come back. Forbidden from speaking to Cilla, Evie secretly sends her letters. Evie writes about her family, torn apart and hurting. She writes about her life, lonely without Cilla. And she writes about the new girl in school, June, who becomes her friend, and then maybe more than a friend. . . . Evie could really use some advice from her big sister. She sends letter after letter. But Cilla isn't writing back"--Provided by publisher.
