Agent Adanna Taylor, known only to those in her field as "The Viper", is an elite government assassin working for the CIA's covert intelligence network called, "The Agency."
Adanna has just completed a six-month assignment overseas and can't wait to get back into the arms of her girlfriend Brenda. However, it is not long before she gets called back into the field. Her quality time with Brenda is cut short when she gets an emergency message from Daniel Jamerson, her boss, and he orders her to go to Miami, Florida and locate government informant Patrick Collins.
Collins has been targeted for elimination by the terrorist organization La Pesta Negra. Still not wanting to take the assignment, Adanna changes her mind when finding out that Deso Alomar, the man she holds responsible for killing her fromer lover, Elena, is involved.
Faced with an opportunity for revenge, Adanna agrees to go to Miami. She soon discovers her line of work is hitting too close to home and is a serious threat to her personal life. This means that the people she cares about most may pay the ultimate price. Quick, precise, cold-blooded, and deadly...this is The Viper. Normally this equation equals death, but her perspective changes when maters of the heart and loyalty become more important.
