Husband-and-wife treasure-hunting team Sam and Remi Fargo try to unravel yet another ancient and cryptic mystery. There are many rumors about the bay off Guadalcanal in the Solomon Islands.

On a hunt from the Solomons to Australia to Japan, what the Fargos find is both wonderful and monstrous - and like nothing they have ever seen before.
