Emily can't remember the last time she left the house. Or spoke to anyone besides her grandmother, beloved children's author Catriona Robinson. After Catriona's death, Emily is at a complete loss . . . until she gets an unexpected letter from the woman she loved most. Catriona has revealed there might be one last, lost unpublished manuscript in her wildly popular book series. And she's left a secret diary and trail of clues that only Emily can follow. From London to Paris to Verona, Emily traces her grandmother's past, finding out more about her family — and herself — than she ever imagined possible. Hopeful and adventurous, celebrates books and bookstores, the power of imagination, and having the courage to shape our own destinies.
