Back again to tie up loose ends and care for her ailing father, Nic is soon plunged into a shocking drama that reawakens Corinne’s case and breaks open old wounds long since stitched.

Daniel and his wife, Laura, are expecting a baby; Jackson works at the town bar; and Tyler is dating Annaleise Carter, Nic’s younger neighbor and the group’s alibi the night Corinne disappeared. Then, within days of Nic’s return, Annaleise goes missing. Told backwards--Day 15 to Day 1--from the time Annaleise goes missing, Nic works to unravel the truth about her younger neighbor’s disappearance, revealing shocking truths about her friends, her family, and what really happened to Corinne that night ten years ago.
