The After Wife by Melanie Summers

After losing her husband, writer Abigail Carson has all but given up on life. Having spent the last year cocooned in her Manhattan apartment, Abigail is suddenly forced to find a new home where she can stretch her dwindling savings. Intent on isolation, she moves to a tiny village in Nova Scotia where she’ll have no one to interrupt her solitude.
Little does Abigail realize that small-town life offers far less privacy than the big city. With neighbors knocking on the door bearing homemade treats and invitations, Abby soon finds herself immersed in the lives of the people of South Haven. She forms an unlikely friendship with Liam Wright, the handyman renovating her dilapidated cottage, and his daughter, seven-year-old Olive.
As the dark cloud engulfing Abigail lifts, she starts to think she may have found love again. But just as Abigail is ready to leap, she discovers Liam carries with him a shocking secret that will ultimately cause everything to unravel. Abigail must decide if she will turn away from his pain or open her heart in the most hopeless of circumstances.
