As the head of an FBI Behavioral Science team, Anne Burge hunts serial killers. With twenty-two captures and convictions, her team is among the best in the Bureau. In Florida, a series of gruesome killings is escalating. Nicknamed “Pussy Venom” on the internet, Anne’s latest serial killer rapes and then injects snake venom into his victims’ bodies. Anne’s ability to track and find serial killers is because of her father, a notorious serial killer called The Postman. For the first nine years of Anne’s life, her father used her as bait to lure his victims. She saw how it was done firsthand. As Venom’s body count grows and accelerates, Anne begins to realize that these killings are connected to her own past, and that she’ll have to face her deepest fears to find the killer.
