It’s 1950. Tissue samples, managed by the Los Alamos research group, have been stolen out of a lab in San Juan, arousing the interest of FBI station chief John Spillers, a 500 year old werewolf. The theft was orchestrated by Jesus Santiago, a Taino man who’s been itching for revenge since 1518. Complicating things is Captain Sepulveda, who runs the detention facility holding Santiago. Sepulveda's men were killed in a classified Los Alamos bio weapons exposure trial, and he wants answers. The Masters is a violent sci-fi romp through history, folklore, and science with a dash of magical realism.
