Hell has a problem. The battle with the Kun'Sumani rages on. There's a cure now, but it can't be produced fast enough to end the invasion. Too many warriors have been killed, too many orphans have been left behind. Hell needs help, and there's no way to bring it in. Killian and Eloise have a problem, too. Centuries of torture have taken their toll on Killian. It's been almost a year since the last time he and Eloise got down to business, and their relationship suffers for it. Eloise has rewritten her life to help him, but everything she does seems to make it worse. Here comes Abe to mess everything up. The Prince of Lust, the fallen angel Abaddon, also known as dad to Eloise, has a plan to kill three vampire bats by elevating Killian to Prince of Wrath and converting Killdevil Castle into a waypoint, boarding school, and training facility. It seems like the smartest plan he's ever had. Until he tries to kill a fourth vampire bat by challenging Killian to get it on with Eloise, ruining everything. No surprises there.
