Commando Shark by Brian G. Berry
Viki Vixen, Commander of the Violent Vixens, a CIA Special Forces team, leads her Huntresses against the notorious Cuban commander General Ernesto Martinez. In a raid to spoil his plans, the Violent Vixens fall to a clever ambush that leaves Viki's team dead. Close to death herself, Viki fights her way to the sea for escape. Once free of the Soviet and Cuban soldiers, she swims into a crazed pack of sharks. She prepares herself for battle, but what they offer instead is lust. What follows her violation, is a birth of a new breed. One that will link into her memories, and avenge her fallen team.
