The Mariner by Tom Golden

A castaway in a strange land.

A dying god, prisoner of a mad king.

The final conflict in an ancient war.

When Raina Marbuck, a mariner aboard the Fortune, is offered hefty pay to help transport a royal expedition with a secret purpose into the broken lands beyond the kingdom, she can't refuse. Leaving her young daughter behind, Marbuck departs into the wastes, certain she'll be returning soon.

Instead, she finds herself embroiled in an odyssey that will take her from the blackest depths of terror, trapped aboard a slaver's galleon, to the intrigues of a forgotten desert realm, pulled between the power of two gods.

In order to return to her daughter, Marbuck must make a duplicitous bargain with one of these gods, one that will force her to confront her own king and the aftermath of his expedition's cosmic meddling. Faced with the end of everything, Marbuck, a simple mariner, will find her own desires balanced against the fate of the world...
