Defiant (The Skyward Series Book 4)

Defiant by Brandon Sanderson — the final book in the bestselling Skyward series — brings Spensa’s epic journey to its thrilling conclusion.

After escaping the Nowhere, Spensa returns forever changed by what she’s seen among the stars and the truths she’s learned about her Cytonic powers. But the Superiority’s war for galactic control rages on, and humanity’s survival hangs by a thread.

Armed with new knowledge and allies, Spensa must use everything she’s learned to stop the enemy once and for all. Yet victory may demand the ultimate sacrifice — her identity, her friends, and even herself.
