Tress of the Emerald Sea is an epic fantasy novel written by American author Brandon Sanderson.

When the ship was ambushed by pirates, Tress and Huck escaped and joined the crew of the notorious Crow's Song.

Tress quickly endeared herself to the fearful, ragged crew, including the quartermaster Fort, carpenter Ann, helmsman Salay, and the eccentric Hoid, the latter of whom had suffered a curse once inflicted by the Sorceress.

To confront the Sorceress, Tress must overcome three trials: the Midnight Essences, giant golden statues, and a fortified tower.

However, the paranoid Huck secretly sabotages the ship's food using Hoid's magic, causing Tress to distrust and imprison him.

Fort controls the Midnight Essences, and Hoid, with his own curse now lifted, halts the Sorceress' attack upon Tress and the crew, forcing her surrender.

[1][5] Kirkus Reviews called the novel "a fantasy adventure with a sometimes-biting wit", and praising it for the engrossing worldbuilding, appealing characters and sense of humor.

She described the novel as "a fairy-tale Cosmere adventure filled with fun characters" and said "Sanderson’s gift for creating unique settings really shines".

[7] David Wiley of Open Letters Review praised the novel for its "punchy pacing, witty humor, vibrant characters, and fascinating magic systems", yet he criticized the narrative and too many Cosmere-related subtleties added to the plot.
