We've all had nightmares. But what if you started to believe your scary dreams were somehow related to a series of grisly murders? Ethnobotanist Gareth McKenna faces just such a dilemma. In Of Blood and Blackwater, he struggles to piece together nightmares he can't quite remember. Dreams that leave him thinking of the years he spent living with an indigenous Amazon tribe. When a curare-laced dart recovered at one of the crime scenes matches the analytical fingerprint from a sample he collected years earlier in the Amazon, Gareth finds himself the lone suspect. His life begins to crumble as his name surfaces in the press. With nowhere else to turn, Gareth must do the unthinkable, he must look beyond science and trust in the strange dreams that offer the only clues to the killer's identity. He travels back to the Amazon, and deep in the rainforest, makes a chilling discovery. One that sends him racing home, desperate to stop a brutal murderer intent on destroying his family.
