A year after the events in Amazonia, Blake and Shale have joined as one. But only days after celebrating their union, a savage storm hits the Amazon village, unearthing a long lost secret–a clue to the location of a sacred relic, which was once stolen from the Amazon tribe.
Accompanied by Kale and Amber, Blake and Shale set out on a quest to reclaim the treasured artifact. Away from the safety of their village, the four women encounter thieves, deadly foes, and predatory animals.
Their search leads them underground to a vast cave system, where darkness is a constant enemy, and one mistake in the perilous terrain could mean death.
As echoes from the past come back to haunt them, Blake and Kale are both put into life-threatening situations. With only time to save one, Shale is faced with an impossible choice–her wife or her twin? Who will she choose?
