City of the Dead - Chris J. Cranford

Grimm saved his friends in Grafton. But he also lost the Key to Azazel.

Not just any key, but the Key. The one Solomon imprisoned demons in.

Millions will die if Azazel opens the Key. But Grimm's friends suffer their own problems. Problems that could kill them.

The choice is simple. Grimm can save his friends or the Key. In City of the Dead, the sequel to Ghost Town, Grimm wonders if he can do both.
