Every year on March 26, Verity Peterson visits Ogunquit Beach, where she puts a handwritten message into a bottle and launches it into the waves.

And finally, one phone call may change everything...

Every June, the quiet beach town of Ogunquit is overtaken by wealthy families who hire local young women like Amy Latimer and Hayley Franklin to care for their children. Best friends since childhood, Amy and Hayley are eager to secure lucrative summer jobs. Amy wants to finance her upcoming move to Boston. Hayley hopes to earn enough money so that her mom can leave her abusive husband. But the passing weeks bring complications and revelations, altering friendships, testing the bond between mothers and daughters, and proving that the ripples from a single season can last forever...
