Lily's Crossing

This year, as in other years, Lily has planned a spectacular summer in Rockaway, in her family's cozy house on stilts over the Atlantic Ocean. But by the summer of 1944, World War II has changed almost everyone's life. Lily's best friend, Margaret, and her family have moved to a wartime factory town, and worse, much worse, Lily's father is on his way overseas to the war.
There's no one else Lily's age in Rockaway until Albert comes, a refugee from Hungary, a boy 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 when they join together to rescue and care for a kitten, they begin a special friendship. For Lily and Albert have their own secrets to share: they both have told lies, and Lily has told a lie that may cost Albert his life.
