DARK MOON: THE BLOOD ALTAR novel was written by HYBE in collaboration with the K-pop sensation ENHYPEN in this hardcover edition.

The seven most popular boys at Decelis Academy all share a secret - they're vampires. The brothers have been on the run for years after a mysterious enemy burned their orphanage down, and just when they think they've finally found a bit of respite, the appearance of new student Sooha changes everything! Beginning as a budding friendship after Sooha is saved from a monster attack by the oldest brother, Heli, their lives quickly take a turn for the strange. Why is it that all of them have supernatural abilities and share dreams about a princess and her knights? As Sooha and the boys find themselves inexplicably drawn together, a dark moon rises ominously overhead... And their fated love just might deliver a deadly bite.
