Lily's Crossing by Patricia Reilly Giff (Paperback)
There’s no one Lily’s age in Rockaway until the arrival of Albert, a refugee from Hungary with a secret sewn into his coat. Albert has lost most of his family in the war; he’s been through things Lily can’t imagine. But soon they form a special friendship. Now Lily and Albert have secrets to share: They both have told lies, and Lily has told one that may cost Albert his life.
