Shadow of Light by Molly E. Lee
Hell is no trip to Disneyland, but even Harley isn't prepared for what she meets in each new circle. With Draven's twin brother at her side, she takes each new horror face on. Fear isn't new to her, but the things that slither in this darkness may just ruin her in the end. The clock is ticking as they try to locate the ancient artifact that will strengthen her powers and help her vanquish the Twelve Greater Demons now wreaking havoc on the world above. The ones she let free in order to save Draven's life. Now he's somewhere in this Hell, and if she doesn't find him or the artifact, she'll have succeeded in being the best Antichrist ever-and the world will pay for her choices. With each new obstacle, she and Raiden grow closer, her soul torn in two as they search for his brother. Each step gained feels like two steps back in this hell-hole, but the deeper they go, the more she feels her powers grow. The world above is at stake, but down here? Nothing is as it seems. With Raiden at her side, Draven in her heart, and an artifact that will decide her fate, Harley will have to face every dark piece of her soul in order to get them all out of there alive.
