An old prophecy, foes at at every turn, and in the middle, Max and Eira. When a mentor of Max’s, Professor Donovan Claron, summons him to be privy to his latest experiment, Max doesn’t quite know what to expect, but it certainly wasn’t her. They have her in a cage and treating her like a lab rat. From the moment Max sees her, he knows what he has to do: betray one of the people he’s closest to to save the woman that his heart tells him he needs. Neither of them quite understand what they're getting into once she's freed, however. A whole underworld of boogeymen and myth and legend opens up before them, and they have no choice but to charge right in.
