Fellow orphans, amateur vigilantes, and members of the Santitos, Loup Garron-the fugitive daughter of a genetically engineered "wolf-man"-and Pilar Ecchevarria spent their entire lives under military occupation in a cordoned off Texas no-man's-land that used to be called Santa Olivia, now known as Outpost 12. But now they're free, and they want to help the rest of the Santitos escape. During a series of escapades, they discover that Miguel Garza, Loup's former sparring partner and reprobrate surrogate brother, has escaped from Outpost 12 and is testifying on behalf of its forgotten citizens-at least until he disappears from protective custody. Driven by a sense of honor, Loup vows to rescue Miguel, even though venturing into the U.S. could mean losing her liberty. Driven by love and loyalty, Pilar promises to help her.
