“Defiant” is the fourth and final book in the Skyward series by Brandon Sanderson¹². The story revolves around Spensa, who has made it out of the Nowhere, but what she saw in the space between the stars has changed her forever¹².

She came face to face with the Delvers and finally got answers to the questions she’s had about her own strange Cytonic gifts¹². The Superiority didn’t stop in its fight for galactic dominance while she was gone¹². Spensa’s team, Skyward Flight, was able to hold Winzik off, and even collect allies to help with the cause, but it’s only a matter of time until humanity—and the rest of the galaxy—falls¹².
