Where There’s Smoke by E. B. Vickers

In this fast-paced thriller, eighteen-year-old Calli finds herself alone after the loss of her father—until a bruised and broken girl shows up on her property, forcing her to face the present, rethink her future, and unearth the skeletons of her own past.

Life has never been easy in the small desert town of Harmony, but even on the day Calli Christopher buries her father, she knows she is surrounded by people who care about her. But after the funeral, when everyone has finally gone home, Calli discovers a girl on her property. A girl who’s dirty and bruised and unable to speak. And petrified.
Calli keeps the girl secret—well, almost secret. She calls her Ash and begins to nurture her back to health. But word spreads in a small town, and soon a detective comes around asking questions about a missing girl from another town. But these only raise more questions–about Ash and about the people Calli knows well. Still, she must ask: is Ash in danger…or is she the danger?
