The Underworld is real. Spencer Perry knew it was a long shot when she started searching for a way into the Underworld, the ancient Greeks resting place for the dead. But three months ago her boyfriend died and now she’ll do anything to get him back, even make a deal with the devil himself. Only, Hades isn’t what she expected, and neither is the proposal he offers. In exchange for Micah’s resurrection, all she has to do is spend every night for the next year down below. From the very first meeting the god makes her feel things she shouldn’t, but she takes the deal anyway, knowing in the end it’ll be worth it. Except, as soon as their bargain begins, strange things start happening. People are being attacked by invisible forces, and all signs point to the God of the Underworld being responsible. Has Spencer inadvertently unleashed hell on earth?
