The First Glader

Ada was the first Glader.
The girl WICKED never meant anyone to remember. The girl they built the Maze around. Years before Thomas ever opened his eyes inside the Box, Ada learned how to survive-alone-mapping stone corridors, battling the mindless monsters she had no name for, and burying the boys she failed to save. By the time the Glade fills with life, Ada is already its ghost: brilliant, terrifying, and carrying more grief than a body should withstand.
Nick taught her how to hope.
George taught her how to love.
And Thomas...
Thomas arrives just in time to watch everything burn.
When he triggers the beginning of the end, Ada's world collapses. Old loyalties fracture, friendships turn deadly, and the Maze-her Maze-becomes the center of a war she never asked to fight.
But Ada is no longer the girl WICKED created.
She is the mapmaker, the protector, the one who runs into danger instead of away from it. Beside the Gladers she raised-and the boy she never meant to fall for-Ada escapes into the Scorch, plunges into the Last City, and challenges WICKED face-to-face. Through raids, betrayals, heartbreak, and revolution, she discovers the truth hidden even from herself:
WICKED didn't steal her life.
They stole her identity, her family, and her destiny.
And she intends to take all of it back.
But saving the world has a cost.
Saving the people she loves has an even greater one.
