From New York Times bestselling author Mackenzi Lee comes a thrilling tale set in the world of the Masters of the Universe live-action film, where Eternian warrior Teela must decide how much she’s willing to sacrifice to save the people—and home—she loves.

A FALLEN KINGDOM
Four years after Skeletor decimated the kingdom of Eternos, Teela and the scattered refugees of Eternia survive by never staying in one place for long. When a brutal storm of acidic rain deep within the Evergreen Forest leaves their camp ravaged and hope at its thinnest, some, like Teela’s friend Locke, begin to plan for a future beyond Eternia. But Teela knows her father Duncan, the once-mighty Man-At-Arms, won’t survive leaving the land he swore to protect.

A FORBIDDEN ALLIANCE
Desperate to save her people, Teela ventures to Darksmoke to bargain with the ancient dragon Granamyr. He bestows upon her a vial filled with a mysterious, powerful elixir—and no instructions on its use. Enter Evil-Lyn, Skeletor’s ruthless second-in-command, who intercepts Teela with a dangerous proposal: an alliance. In exchange for the vial’s secrets, Teela and the Heroic Warriors must someday help the sorceress overthrow Skeletor himself.

A MAGIC THAT COULD SAVE—OR DESTROY—THEM ALL
The vial heals the sick and brings food back to empty tables—until the forest around the camp begins to change. Rivers vanish. Trees peel to bone. Creatures flee. As the land around them withers at an ever-increasing pace, Teela must confront an impossible question: Has the very magic she used to save her people doomed Eternia instead?
