Alex Cross investigates a series of baffling murders while balancing a family crisis that threatens to upend his entire world in this thriller from the world's #1 bestselling author, James Patterson.

Alex Cross is a brilliant psychologist—and a relentless hunter of killers for the FBI and DC Metro Police.

To his beloved Nana Mama, he’s still the boy she raised—and every morning, as he straps on his service weapon, she’s reminded just how dangerous his world has become.

But in Washington, DC, there are places even the police don’t go—an unseen underworld where violence thrives and rules don’t apply. And this time, Alex is stepping straight into it.

Each move pulls him deeper into the dark—and closer to a case that could shatter the promise he made to Nana … and cost him everything he holds most dear.
