When the Box opened and a pair of twins emerged-Newt and his sister-the Glade changed forever. She grows up in a world of walls and rules, learning to survive in the shadow of her brother, the calm second-in-command who everyone trusts. But the Maze has a way of testing loyalties... and destroying even the strongest bonds.
Then Thomas shows up.
Suddenly the patterns begin to shift. The Maze is changing. Secrets start to unravel. And she finds herself caught between protecting her brother and trusting the boy who might be the key to everything-or the one who tears their fragile world apart.
As danger closes in from every side, she'll have to run, fight, and uncover the truth behind why both twins were sent up.
Because in the Maze, nothing is an accident...
and surviving together might be the hardest challenge of all.
