Harry Houdini escaped every prison built to hold him.
Death was supposed to be the exception.
One hundred years after his final performance, fraudulent medium Cassie Sparkowski attempts a livestreamed s ance-and accidentally brings Houdini back. But he is not alone. Behind him waits an endless darkness filled with the restless dead...and something far worse.
As Houdini opens door after door between worlds, ghosts begin returning to the people and places they left behind. Some come home in love. Some come hunting for vengeance. All of them carry a piece of the darkness with them.
Now Cassie and FBI agent Bradford Carter must stop the greatest escape artist who ever lived before he completes his final act: opening the door that can never be closed.
