From 14 to 25-years-old, Sam Martin's an afterthought in Nimbus. All this world wants is for him to leave, for him to go outside the steel doors and survive in the vicious, untamed wilderness for 11 years. After all, every person who has ever called Nimbus home has done it. Every. Last. One. Or so he was told. Outside the walls of Nimbus, Sam's faced with horrors unimaginable to someone who's spent his whole life stuck behind the steel. Now, he must fend off evils he's never seen, horrors he never could have expected-all while fighting himself. After all, he's just a kid. A kid who never knew how heavy fate could truly be.
