Seventeen year old Hyde Carver has spent his entire life in a doomsday bunker called Savior’s Landing—an underground city opened up by lottery to a lucky few after The Great Collapse. But Hyde doesn’t feel lucky.

The billionaire who built Savior’s Landing, Viggo Stone, promised them a peaceful democratic utopia, a place where everyone could vote, pursue their dreams, have plenty of food to eat, and keep all of their limbs intact.

He lied.

The newborn babies that Hyde helps bring into the world are all mysteriously dying and a strange bioluminescent mushroom is creeping out from between the cracks in the walls. When Viggo does the unthinkable to Hyde’s family, Hyde is forced to find his way to the surface with his little sister, Alice, a girl so special that even the plants reach out for her when she walks by.

Juno was raised in chaos on the surface of the Earth—a planet ruled by parentless children who only know how to steal and kill to get what they want. She knows nothing of Savior’s Landing and just wants to be left alone in her remote cabin in the Rocky Mountains. Things would be perfect if only she didn’t have to deal with the drug-crazed Moonys whose addiction to the spreading Moondust makes them unpredictably fast and strong. 

When Hyde meets Juno, a life-or-death decision starts them on a journey to try and reunite Hyde with his sister after they become separated. Hyde needs to find Alice before her captors find out what she’s really capable of and Juno needs to learn that she really can love other humans.
