Keepsake by Sarina Bowen

There's a first time for everything.

Lark Wainright used to be fearless. Her life was a series of adventures, each one more exhilarating than the last. But her recent overseas adventure was one too many. Now she's home and in one piece. Mostly. But her nights are filled with terror.

When her best friend offers her a stay at the orchard in exchange for help at the farmers' markets, Lark jumps at the chance to spend fall in Vermont. But her nightmares don't stop. Desperate to keep her fragile state a secret, she relies on the most soft-spoken resident of the Shipley Farm to soothe her when her dreams prove too much.

Zachariah is a survivor, too. It's been four years since he was tossed aside by the polygamist cult where he grew up. He's found a peaceful existence on the Shipley's farm, picking apples and fixing machinery. But getting thrown away by your own people at nineteen leaves a mark on a guy. He doesn't always know what to make of a world where movie quotes are the primary means of communication. Before hitchhiking to Vermont, he'd never watched TV or spoken on the phone.

Actually, there are a lot of things he's never done.

Zach and Lark slowly grow to trust one another. One night they become even closer than they'd planned. But Lark may still be too broken to trust anyone. When she pushes Zach away, he will have to prove to himself that he's good for much more than farm labor.
