There is a deeper game being played, and it's being played out with Pandora as the pawn. With Katie and Pandora going to the deepest depths to track down some killers, Pandora’s greatest temptation will be in her grasp. Can the two of them, plus help, figure out the real danger or will they encounter it without preparation? Further, will they figure out how to handle a Leviathan that is larger than New York City? Have the depths of Hell finally revealed a plot centuries in the making? Will Katie and Pandora trip something to throw all of their success into question? While Katie and Pandora are challenged, we find all of her friends dealing with attacks of their own. Can Korbin and the team help other areas of Earth protect themselves? The strength of this team is they have each other's back. Succumbing to temptation is a choice. Will Katie know what it is in time to help Pandora through it, or will Pandora recognize the subtle trick her ex-husband has delivered gift-wrapped?
