Until I Find You by Rea Frey
What would happen if a mother reached down into her three-month-old son's crib and discovered that the baby lying there was not her own? What if none of her friends noticed the subtle differences that made it so obvious to her? What if no one believed the blind widow at all? I absolutely loved this domestic thriller. Rebecca is such a likeable character and the author did such a great job of pulling me into her world. The ending fell a bit flat, but the journey to get there had me holding my breath the whole time.
