Sally Crow has spent years haunted by nightmares of ravenous wolves stalking her through a dark forest.

Now the nightmares are coming true.

After surviving enemies who should not exist and creatures no one can explain, Sally, her husband, and their son Steven are placed inside a heavily guarded safe house. Protected by an army of armed agents, far from the wilderness of her dreams, Sally allows herself to believe the worst is finally behind them.

Steven is safe. Her husband is safe. For one fragile moment, life is good.

Then their enemies find them.

The fortress falls. The agents fail. And Sally is forced to run, hunted by forces both real and impossible. But no matter how far she flees, the dark forest from her nightmares waits for her.

When Steven is abducted and taken into those woods, Sally must face the terror that has stalked her dreams for years.

Because this time, the wolves are real.

And they are not the only monsters waiting.
