In the fourth Demon Trappers novel, Riley faces the final battle for humanity and Beck's heart—and Hell is the least of her problems.

Now that Riley’s managed to (just barely) fend off Armageddon, everything’s changed. Well... most things. After their passionate kiss before the big battle in the cemetery, Beck is back to treating her like a little girl, as if nothing ever happened. While she’d love to just tell him off and move on, Riley vowed to take care of Beck the way he’s taken care of her since her father’s death—but she’s about to get a whole lot more than she bargained for.

When she’s commissioned to go with Beck to his hometown and help him care for his dying mother, they stumble too close to a dark and murderous secret, one that Beck fears will drive Riley away from him forever. As chaos breaks loose, Riley may be Beck's only hope for redemption... and survival.

Meanwhile, up in Atlanta, it’s quickly becoming clear that Heaven may have won a battle, but the war is far from over. Riley and Beck face a stormy future, as Lucifer's ex-right-hand-man, Sartael, proves himself to be more resilient than anyone thought. He has Atlanta in his grip and is about to begin a brutal war with the prince of Hell.

As the seconds tick down toward a final confrontation, it's up to Riley and the man she loves to finally defeat their old enemy, or lose everything they've fought for.
