The Good Guy on My Porch by Katharine Sadler

Dilly Thompkins is a liar. She’s been lying to everyone, even her closest friends, for more than a decade. She lies to keep a secret, a secret not entirely her own, a secret that will change the way everyone in her small hometown of Catalpa Creek looks at her and treats her. Her lies and her secret have made it important that she never lets anyone get too close, not just because she needs to keep her secret, but because loving someone, getting lost in another person, is dangerous for someone like Dilly.
Oscar is Dilly’s new neighbor and he’s determined to find out why this woman, a woman he’s been drawn to since their first meeting, looks so sad so often. He’ll do just about anything to make her smile, but the more he gets to know her, the more he cares about her, the more he knows he stands to lose. He moved to Catalpa Creek for a simpler life, and Dilly’s secret may be more complication than he wants.
As the people who care about Dilly begin to question her carefully laid lies, she shoves her own walls up higher and goes on the defensive. Her world is crumbling and the only place she feels safe anymore is in Oscar’s arms.
