Amerikarate (Amerikarate #4)

Sam Kickwell and his partner in karate and love, Agent Cynthia Weaver, jump-kick their way into the belly of the beast - a karate-gang-filled mansion! They will have to punch, kick, stab, shoot and even sex their way through one of the most vengeful, weapons-heavy, black-belted gang after another just to get near America's greatest enemy... evil dictator, Neon!
