The Death List by Thomas R Clark
Ronnie Dark is having a bad day. Facing rock bottom after losing his job, losing his wife, and being served eviction papers, he hatches a dark and desperate plan for revenge on his ex-wife.
Meanwhile, the home's former inhabitant, Patrick Dermotty, the infamous Balloon Boy Killer, has escaped from the institution holding him. Patrick has one goal: to return to his home and finish what he started thirty-five years ago—the resurrection of an ancient, dark deity.
Ronnie Dark’s bad day is going to get worse before it gets any better.
