As Dr. Marina Singh embarks upon an uncertain odyssey into the insect-infested Amazon, she will be forced to surrender herself to the lush but forbidding world that awaits within the jungle. Charged with finding her former mentor Dr. Annick Swenson, a researcher who has disappeared while working on a valuable new drug, she will have to confront her own memories of tragedy and sacrifice as she journeys into the unforgiving heart of darkness.

What Marina does not yet know is that, in this ancient corner of the jungle, where the muddy waters and susurrating grasses hide countless unknown perils and temptations, she will face challenges beyond her wildest imagination. Marina is no longer the student, but only time will tell if she has learnt enough.
