Five years have passed since the events in New York City. With Thirteen dead, Gavin and Ashley relocated to a small Ohio town, his life as a demon hunter nothing more than a memory. Meanwhile, Kayla and Jamie have started a family in Chicago, trading one metropolis for the next as they adjust to the ever changing world of parenthood. But peace is short lived as the past comes back to haunt them. Though Triton is gone, his legacy has continued in the form of a secret society known only as The Order. Soon Ashley disappears, taking with her an unexpected secret, leaving Gavin to pick up the pieces. Now hunted by Triton's partners and an assassin on his trail, Gavin is forced into an unexpected partnership as he races against time and fights to save Ashley, all the while falling deeper into darkness.
