Cherry Tree Lane (The Wiltshire Girls #1)
Anna Jacobs

But Mattie gets lost in a thunderstorm, collapsing from exhaustion, sure she’s about to die. Widower John Kemble goes to investigate his son’s news that there’s a dead body in the lane, and brings the stranger home. She’s young and attractive, suffering from pneumonia and with his wife dead, there’s only him to tend her.
This leads to choices and opportunities Mattie could never have imagined. Will she have the courage to take the chance on a very different future?
