A chance encounter sparks an unrelenting web of lies in this stunning new psychological thriller from the New York Times bestselling author of The Good Girl, Mary Kubica 

She sees the teenage girl on the train platform, standing in the pouring rain, clutching an infant in her arms. She boards a train and is whisked away. But she can't get the girl out of her head…

Heidi Wood has always been a charitable woman: she works for a nonprofit, takes in stray cats. Still, her husband and daughter are horrified when Heidi returns home one day with a young woman named Willow and her four-month-old baby in tow. Disheveled and apparently homeless, this girl could be a criminal—or worse. But despite her family's objections, Heidi invites Willow and the baby to take refuge in their home.

Heidi spends the next few days helping Willow get back on her feet, but as clues into Willow's past begin to surface, Heidi is forced to decide how far she's willing to go to help a stranger. What starts as an act of kindness quickly spirals into a story far more twisted than anyone could have anticipated.
