After learning the boy she loves has been kidnapped by the Sorceress, a young girl best known as Tress navigates the many perils of her world as she leaves the safety of her desolate island for the first time.

“Tress of the Emerald Sea,” the first of four “secret” novels to be released by fantasy author Brandon Sanderson, takes a more lighthearted tone than most of his books but is regardless compelling with its blend of high fantasy and classic fairy tales.

Although part of the Cosmere — the fictional universe many Brandon Sanderson series take place in — “Tress of the Emerald Sea” leans away from the in-depth world-building and complex magic systems typically featured in his books, instead offering the reader a childlike sense of adventure while following Tress as she faces deadly spores and builds her cup collection. This playful nature is largely due to the narration by Hoid, a fan-favorite character appearing in every Cosmere book, who adds his own commentary throughout the story. Furthermore, the beautiful illustrations by Carlos Guimerá sprinkled in the chapters immerse readers in the world.

While “Tress of the Emerald Sea” is a delightful addition to the Cosmere, it certainly does not inspire the same thrill and fervor as Mr. Sanderson’s other books, like “The Way of Kings.” Instead, it is the perfect light read for fans of his work or anyone looking for an introduction to the fantasy genre.v
