If you love Sam and Dean, then you’re going to adore The Blood Sisters! Hunting demons, kicking ass and saving people is what they do. When an evil gang spreads demon essence drugs throughout the mid-west, Jessica and Amanda Blood are hot on their trail. Until Amanda is kidnapped by demons eager to collect the bounty placed on the sisters’ heads by queen of the underworld. Jessica will go to the ends of the Earth to find her healer sister, before Amanda is sacrificed and her pure blood used to open the gates of hell. But to get there, Jessica must ride with bad boy demon hunter Duncan Jasper and his gang. Too bad the only thing tougher than fighting demons is fighting her attraction to Duncan. Duncan Jasper left Jessica once, on his own dangerous mission. Now he’s back, and determined to keep her safe in his arms, no matter what—if she'll let him, that is. But with demons charging from the front, the underworld gunning from behind, and a spy in their midst, Jessica and Duncan's fight to save Amanda—and humanity—is just beginning.

The queen of the underworld has a new play toy and her name is Jessica Blood. Bad boy Duncan Jasper and passive healer Amanda Blood are on the run for their lives with a horde of demons on their tale. The queen of the underworld, Lourdes, wants Amanda to free Lourdes from her prison and it’s all on Duncan to keep this from happening. But Amanda’s soul is fractured and bleeding thanks to the torture she suffered at the hands of the high-level demon, Vaughn. Now a painful ritual is her soul’s only chance at survival. If Duncan fails, Jessica Blood may never be free from the chains that bind her to Lourdes. Demons swarm to their location and Jessica walks right into a trap they’ve set for her. But to cure her sister, Amanda will have to embrace the pain and welcome the beauty of death. All before they get ready to stand off against Lourdes and the demons of hell, coming to claim their souls. Hold onto your seats! Long-held family secrets and heartache are about to be revealed.

Lourdes has been slain and the new queen of the underworld has been chosen. It was the day the Blood sisters had been striving for. The day where they would be free of Lourdes and could go back to living normal lives, but with the underworld’s throne empty, the Earth plunges into chaos. Rivers turn black, demons run amok, with more chaos is about to be unleashed. All the while demon hunter, Duncan Jasper, is prisoner of the enemy. Jessica will stop at nothing to free him from Vain, a bounty hunter who trades in the lives of humans. Getting into her stronghold won’t be easy, and Vain will be expecting a fight, but what she won’t be expecting is Jessica’s secret weapon. The newly crowned queen of the underworld, her very own sister. Jessica hopes Amanda can resist the dark magic now surging through her veins long enough for a special artifact—The Ruby Heart—to be found, the one thing that can purify Amanda’s heart and break the awful curse. But Amanda has other plans. If she sacrifices herself to the underworld, she hopes to do one better. Kill the demons from the inside and free the trapped souls being tormented for an eternity. One way or another, it will surely come to sister vs sister in a full-scale war. All in the name of Blood.
