It’s been 10 years since Ellie disappeared, and Laurel’s never given up hope of finding her daughter. But now, she no longer has a choice in the matter. It’s time to let go.

Before she knows it she’s meeting his daughters, and his youngest Poppy takes Laurel’s breath away. Because Poppy is so like Ellie was at that age. And now, all those unanswered questions that have haunted Laurel come flooding back. What happened to Ellie? Where did she go?
