It's early May in the small English village of Finch and the air is crackling with excitement: A newcomer is about to move into Pussywillows, a riverside cottage with a romantic reputation. Will the cottage's newest resident prove yet again its enchanting ability to matchmake?

But when Crispin Windle arrives, no one knows what to make of him: Seemingly a loner, he repels every welcoming gesture and appears altogether uninterested in being a part of the community. Soon, the townspeople have all but dismissed him. Only Lori and Tommy Prescott, a young army veteran who recently moved to Finch, refuse to give up. They orchestrate a chance meeting that leads to a startling discovery: a set of overgrown ruins. They are, Aunt Dimity shares, the remains of a Victorian woolen mill that once brought prosperity to Finch.

As the three explore, they stumble upon the unmarked graves of children who died working at the mill. Heartbroken, Lori, Tommy, and Mr. Windle get to work on the seemingly impossible task of identifying the children to give them a proper burial. And as Mr. Windle works tirelessly to name the forgotten children, he slowly begins to open up—giving the romantic cottage a chance to heal his heart as well.
