Emily Ackerman has traveled the world, her constant compass and companion a book of letters her mother left for her when she died. With no father in the picture, her mom's advice has been her only true north. But when professional failure leads Emily back to Nantucket to renovate and sell the family cottage she inherited, she wonders if her mom left advice to cover this . . . especially when her grandmother arrives to "supervise." And especially when her heart becomes entangled with Hollis McGuire, the boy next door–turned–baseball star who's back on the island after a career-ending injury.

As sparks fly between her and Hollis, Emily is drawn to island life, even as she uncovers shocking secrets about the tragic accident that led to her mother's death. With her world turned upside down, Emily must choose between allowing the voices from her past to guide her future or forging her own path forward.
