Emma’s world is falling apart, and Kade, the only one who seems to hold her together, is missing. With death lingering right outside their door, decisions must be made before it’s too late. The Midway has refused to send help, so they are left to seek out the only other who can stop Lucian. A perilous quest sends Emma and a few Guardians into the Underworld, where the unimaginable abide, to beseech the Prince of Darkness himself. Lucifer. Now, they must endure the deadly levels of Hell, which not one …mortal or immortal… has ever survived. Prepare for love, loss, and the unexpected.
