Primal Fury — Jack Silkstone

Beautiful young women are being kidnapped and sold into sexual slavery by a ruthless crime syndicate that the law can't -- or won't -- touch. But after years of terror and abuse, one victim manages to strike back…with the help of PRIMAL. Now, the covert vigilante team lays siege to a medieval-era castle where the barbarism of bygone ages is alive and well. Once PRIMAL's deadly operatives bring high-tech weapons and razor-sharp combat drills into play, they teach the flesh-trade slavers a lesson in preserving human rights…and punishing inhuman wrongs. But when one of the team trades valor for vengeance, it could jeopardize every member on the mission -- leaving them, and the prisoners they're fighting for, at the mercy of the criminal world's most ruthless: the Yakuza.
