"Only fifty Earthlings remain in the galaxy, and I hate every one of them."

Sha-ne, a Martian teen, finds herself floating in a tin can high above Mars on the day everything blew up--literally. She should be apprenticing to become a master engineer, a most coveted position only awarded to exceptional minds by the mysterious Board, who governs the colony on the red planet. Martians develop the technology that runs the colony, but Earthlings are kept separate, used only for manual labour. That's how it's always been.

Sha-ne was just getting settled on the engineering ship with her AI companion, about to meet her mentor and the only other Martian on board, when the colony on Mars burns to the ground, wiping out her entire civilization.

Now Sha-ne has no choice but to join a group of Earthlings who've taken command of the ship, for all of them to survive. Only, she's not sure she can trust Earthlings to do anything right. Especially these rebels.

As Sha-ne and the rebels search other dead cryo ships for supplies, they learn more about the truth behind the disaster that befell the colony and come to realize...

...nothing is as it seems.
