Fool Me Twice by Kara Frei

ANNA BECKER HAS IT ALL. She lives in Montana on her family's successful multi-generational ranch, is engaged to her lifelong sweetheart, and works at a job she loves. But when life throws her a curveball filled with tragedy and uncertainty about her future, she decides to start over in New York. It's there where she meets Kevin Maxwell, a charming, good looking marketing executive who makes big promises for Anna's career. And it's with Kevin that Anna, for the first time since leaving Montana, feels open to a new romance. She finds out the hard way, however, that Kevin may not be exactly who or what he says he is, and she needs to save her career – and herself – before it's too late.
