Trunk No. 3: A Story about a Life-Changing Correspondence by Millington, Allie

From the New York Times-bestselling author of Olivetti, here is the story of a magical--and lifechanging--correspondence.

Trunk No. 3, a worn, wrinkled suitcase with a secret, was perfectly fine with staying closed forever. Until she's stolen by a despondent boy with plans to run away. When a strange note appears in the trunk, however, an accidental correspondence begins to throw everything off course--and toward something, someone, entirely unexpected.

Eleven-year-old Earl Grey has been raised at the Repertorium--a rare library that holds once-forgotten items, each with a tangible memory tied to their very being. She longs to discover life outside of the library, and to find answers about her Before. Little does Earl Grey know that the mysterious pen pal she starts writing to will lead to a life-changing friendship and the unraveling truth of her past.

New York Times-bestselling author Allie Millington weaves together a poignant, uniquely delivered story about connection, worth, and seeing more in the seemingly ordinary--including ourselves.
