The Catachresi are monsters. It is fact; they are ugly, they are grotesque, and they are hungry. They eat humans, or "turn" the human into one of them with their venom to expand their race. Human girls are targeted most, because they can be turned into female Catachresi and give birth to more and more of the horrors. Due to this, human females stay in camps and are protected mercilessly. Except for Clarke. Clarke is a girl with only her father and sister left in her family. When her father is killed by Catachresi while trying to protect Clarke and her sister Meirin, Clarke has only one thought in mind, "Run and protect Meirin." They run, until Clarke is cornered. Clarke makes Meirin run to the army camp not far, and when all seems lost, an army captain saves Clarke from death. With no safe camps for miles, Clarke begs to join the army. The price of her being found out? Death. Painless death, because no one can afford word getting out of a woman being in the army. Even if it means losing the precious women the Catachresi want. Disguising herself as a boy, Clarke is admitted into the army, using her persuasive gun to have the doctor sign her off as okay. But now she faces obstacles, ones she didn't even imagine she'd have to face. Between fighting the Catachresi, protecting Meirin, protecting her gender, and falling hard for the psychotic bastard captain of her squad, Clarke may find one of the most gut-wrenching horrors to ever befall her.
