The Nightwalkers have been forced underground by humanity's treachery. The Oasis, their haven beneath the city of Chicago, has become infected with a fatal fever that is wiping out the last remaining species of Nightwalkers. The dream of a future is crumbling.

Someone must find the Drayada Stone and bring it back to restore life to the dying underground community. It is a perilous journey, and those who take it will be forced to go where no Nightwalker has been in ages: Topside.

The Underground Council appoints this task to a young witch, Zora, who will be accompanied by three unlikely companions she has grown up with in The Oasis. An angel, a vampire, and a werewolf.

There is an ancient evil that stands between the Drayada Stone and the four companions. Zora must look deep within herself to find the power to destroy the biggest enemy of the Nightwalkers, and in so doing, she might just destroy herself.

Will four young Nightwalkers be enough to save a dying species, or will they be buried beneath the rock and rubble of history and forgotten by humanity?
