When Lou Taylor inherits a quaint country cottage and a mobile library full of books from her birth mother, she heads to the small town of Wagtail Ridge to learn more about the woman she never knew. Curiously, the last piece of the bequest is a handwritten letter, the first of many Luca left scattered along the library's route in hopes of finally sharing her secrets with the daughter she had to give up.

The townspeople of Wagtail Ridge flock around Lou, wanting to share the stories of Luca's life, but she knows she must learn about her birth mother in the way Luca intended. Jake Barnes, her new neighbour, offers to help her follow the trail, but weighing on his conscience is a promise he made to Luca - a secret that now stands between him and the woman who's slowly capturing his heart...

As the kilometres fly by, Lou gradually untangles who her mother was and what lay behind the choices she made. At the same time, she finds herself drawing ever closer to kind, handsome Jake. But will it all be enough to keep her in Wagtail Ridge when she has another happy life waiting for her in the city?
