When a chimpanzee of the Amazon saves an abandoned infant and raises him as her own, the boy grows into Raja—the untamed guardian of the jungle. Your decisions shape his fate when treasure hunters invade his world, capturing one of their own: Rita, the fearless woman who sees the man beneath the wildness. Now, love and survival clash in the heart of the rainforest.

As spring dawns, your pro-hero boyfriend's hawk-like physiology has taken hold, transforming the man you love into something more feral and predatory. This is your first mating season with him, and nothing could have prepared you for his overwhelming possessiveness and primal behavior.
