When a Martian leader pulls the strings at the last minute and allows her to accompany her father, Philadelphia knows she must keep her head down or be sent back to Earth. But when a search for her deceased brother’s belongings leads her into a hallway that isn’t supposed to exist, Philadelphia is faced with a question she doesn’t want to answer–the choice between returning to Earth or destroying it.
Maybe his brains can get his family out of prison. Ephesus is a talented young scientist who has spent the last several years of his life in prison for his Christian beliefs. When he is personally summoned to Mars to work for a prestigious governor, who promises his family’s release in exchange for providing a formula needed to complete an important project, Ephesus thinks he may have found his ticket to freedom. But when the project becomes progressively more sinister—and his enigmatic overseer refuses to answer questions—Ephesus begins to wonder if the offer is too good to be true.
Believing the chaos of her adventure on Mars is behind her, 17-year-old Philadelphia faces a restricted but uneventful future as an unskilled drone in the United’s workforce.

The girls soon realize they’re being held hostage to bribe Dr. Nic, Cea’s wickedly genius brother, into resuming work on the infamous superweapon “Red Rain.” Their only option to stop it is to escape. Thrust into the layered, gritty world of the United’s underground, Philadelphia realizes her battle with Red Rain is not over–and this time, turning it over to the authorities is not an option.
