The Spirit Gene

Sparked by a mysterious hallucinogenic experience, Brett Roberts catches his first glimpse of a portal to the supernatural. Desperate to find a biological explanation, he enters the field of biotechnology and dabbles in one experiment after another as the field matures. Brett's quest eventually leads him to the indigenous tribes of the Amazon rainforest, where under the guidance of a Yanomami shaman, his next encounter with the drug yopo proves much more enlightening. An answer to the ultimate question is within Brett's grasp, but not if Alfredo Ruiz can prevent it, a nefarious scientist from S o Paulo who has been following Brett's experiments for years.
