Book excerpt: From Clementine author Sara Pennypacker, this is a poignant middle-grade novel about two foster children who must find a way to work together in order to survive. Eleven-year-old Stella misses her (unreliable) mom, but she loves it at great-aunt Louise’s house. Louise lives on Cape Cod, where Stella hopes her mom will someday come and settle down. The only problem? Angel, the foster kid Louise has taken in. The two girls live together but there’s no way they’ll ever be friends. Then Louise suddenly passes away one morning—and Stella and Angel decide not to tell anyone. Now they have to depend on each other for survival. Now they are forced to trust each other with the biggest secret ever. With great empathy and humor, Sara Pennypacker tells the story of two very different girls who unexpectedly become each other’s true family.
