June Andersen inherits from her aunt Ruby the legendary bookstore “Bluebird.” Soon she discovers among the books unique letters—proof of a long-ago friendship between Ruby and the famous writer Margaret Wise Brown. Since the store is on the brink of bankruptcy, June decides to save it with her find. She turns to Gavin, the owner of the small restaurant next door to “Bluebird.” It seems that together they might have a chance, but June has plenty of secrets, and trusting Gavin turns out to be far from easy.
