Ever since the Bommarito sisters were little girls, their mother, River, has written them a letter on pink paper when she has something especially important to impart. And this time, the message is urgent and impossible to ignore--River requires open-heart surgery, and Isabelle and her sisters are needed at home to run the family bakery and take care of their brother and ailing grandmother.

Isabelle has worked hard to leave Trillium River, Oregon, behind as she travels the globe taking award-winning photographs. It's not that Isabelle hates her family. On the contrary, she and her sisters Cecilia, an outspoken kindergarten teacher, and Janie, a bestselling author, share a deep, loving bond. And all of them adore their brother, Henry, whose disabilities haven't stopped him from helping out at the bakery and bringing good cheer to everyone in town.

But going home again has a way of forcing open the secrets and hurts that the Bommaritos would rather keep tightly closed. Working together to look after Henry and save their flagging bakery, Isabelle and her sisters begin to find answers to questions they never knew existed, unexpected ways to salve the wounds of their childhoods, and the courage to grasp surprising new chances at happiness. . .
