Beneath a sky ruled by gods and monsters, a drowned land spreads — thousands of scattered isles, each its own dominion, each a deadly trap for the unwary.

But for those bold enough to ply these turbulent waters, there is trade to be done and money to be made.

With the seas blazing with war, gods and mages clash to keep their heads above the rising tide. Killian must sail into the storm — and repay the biggest debt he owes, no matter the cost.
