In this riveting domestic suspense debut, a woman's life shatters when she meets a girl she believes is the daughter she lost years ago - and she finds that reclaiming the life she lost might cost her the life she has. Tell Me You're Mine is a story of guilt, grief, and the delicate balance between love and obsession.

Where is the line between hope and madness?

Three women: one who believes she has found her long lost daughter, one terrified she's about to lose her child, and one determined to understand who she truly is.

Stella Widstrand is a psychotherapist, a happily married mother to a 13-year-old son. But when a young woman named Isabelle steps into her clinic to begin therapy, Stella's placid life begins to crumble. She is convinced that Isabelle is her daughter, Alice: the baby that tragically disappeared more than 20 years ago on a beach during a family vacation. Alice is believed to have drowned, but her body was never found. Stella has always believed that Alice is alive, somewhere - but everyone around her worries she's delusional. Could this be Alice?

Stella will risk everything to answer that question, but in doing so she will set in motion a sequence of events beyond her control, endangering herself and everyone she loves.
