The Fix by Mia Sheridan

From bestselling author Mia Sheridan comes a chilling take on second chances, where a brutal break-in comes back to haunt the sole survivor with a new threat—and another victim.

Eleven years ago, Cami Cortlandt’s mother and sister died cruelly in a violent home invasion. The trauma and notoriety still linger, but Cami has managed to build a life in her hometown despite everything she’s lost.
Then one day it all comes rushing back.
A distorted voice on the phone: Would you like a do-over? A disturbing video of a room with bars on the window, trapping a young boy inside who looks achingly, impossibly familiar. Four days to find him.
With the help of Rex Lowe, an old classmate whose past is inextricably tied to her own, Cami races to uncover everything she can about the boy—where he is, who he is, and why she’s the only one who can save him.

But as Cami and Rex unravel one clue after another, the past and present converge in an explosion of secrets they never saw coming…and a truth they never could have imagined.
