A murderous double-cross traps an injured Borsey, Bryar and Ruby deep inside the militarized medical lab. Mal's real objective is revealed to be a deadly new tech. As Mal's mercenaries close in, Ruby is forced to consider a radical scheme for survival, one that will almost certainly sacrifice Rysk's "life."

Demons can't get into Heaven, Angels can't get into Hell but Juniper can. Juniper was once the deadliest mercenary on Earth, but then something went wrong. Now, trapped in a vegetative state on Earth, she's tasked with using her skills to save a soul from the Underworld. Realizing she doesn't need permission to play God anymore, Juniper decides to take matters into her own hands. Should they go to Heaven or Hell? Or is there another option?

Juniper's objective is simple: infiltrate The Ferryman of the Underworld's cargo ship that's transporting tortured souls to Hell, steal a powerful relic, and sneak out. But can she do so with her unexpected and unpredictable ally?

For Juniper and Bheema to continue their fight through the Underworld, they must first come face-to-face with one of the deadliest beings of Hell-Charon, Ferryman of the Underworld-and he isn't happy.
