Could Joe Pickett's foster daughter, seemingly killed six years ago, still be alive? A gripping read from award-winning author and New York Times bestseller C.J. Box.

'Tell Sherry April called.'

A simple message that shakes Sheridan Pickett to the core. For April - foster daughter to Sheridan's parents Joe and Marybeth - has been presumed dead since a brutal massacre that Joe Pickett himself witnessed.

To Joe, it doesn't seem possible that April could have survived. But the person who now begins to text Sheridan is able to recall things only April would know about.

When the texts turn ominous, Marybeth discovers that they are being sent from locations where vicious murders have taken place. Desperate to discover if April really is still alive and if so, to protect her, Joe and Sheridan take to the road with Joe's associate Nate Romanowski.

They will cross paths with a dying Chicago mobster on a mission of his own, as Joe and his family seek to discover the truth, and if the danger is as real as it seems.
