Waking up on the beach in Greece after a midnight party, Cleo, a British-Greek tourist, sees a stranger sitting next to her. The stranger has a giant spider on his forearm.

So begins an incredible odyssey through the nine levels of the mysterious mountain populated by an odd assortment of monsters, demons, and avatars of dead gods. Still grieving the unsolved disappearance of her twin sister Cora, Cleo is thrust into the world whose rules she does not understand and whose inhabitants confound everything she thought she knew about Greek mythology. Confronted by Woven Women, masked huntresses, sentient graffiti, and Mother of Monsters, Cleo has to make sense of it all. And meanwhile, a mysterious Call reverberates in her brain: You have to go up. You have to find your sister.

A story of self-discovery, courage, and breathtaking adventure, Nine Levels is a highly imaginative, innovative, and engrossing retelling of familiar legends with a twist you won't see coming.
