What’s it about?

The story.

Starflight has always wondered about the NightWings: their secret home, their powers, their plans and what it would mean to belong to his own tribe. When he is taken by the NightWings, he finally sees the truth, and it is far more frightening than the legends. Their hidden kingdom is miserable, dangerous and full of secrets, and Starflight has to decide what loyalty means when your own people are doing terrible things. This fourth Wings of Fire book is one of the darker entries in the first arc, with a more enclosed atmosphere, a heavier mystery and a protagonist whose intelligence matters more than physical bravery. Starflight's fear, uncertainty and moral courage give the book a strong emotional shape. It is gripping and rewarding, but the setting and threat level make it less gentle than many middle-grade fantasies.

Why it lands

Why they love it.

Why kids love it

The specific weight is your own tribe being the villains — Starflight finally taken to the secret NightWing kingdom and discovering it isn't the wise mystic place the legends describe but something darker. The Wings of Fire where the moral courage matters more than the physical kind.

  • Being special or chosen
  • Going on a quest
  • Making a difference
  • Secret world
  • Surviving danger

Why parents love it

The first arc's darkest volume — Starflight's discovery that the secret NightWing kingdom is corrupt recontextualises everything the reader thought they knew. Quieter, more anxious, but pivotal. Penultimate-arc-one weight.

Mike Schley

Illustrator · United States

Mike Schley is an American illustrator and cartographer whose primary children's-book role is creating the detailed fantasy maps that appear in the Wings of Fire series by Tui T. Sutherland and other middle-grade fantasy titles. Schley is best known in the wider illustration world for his fantasy cartography on Dungeons & Dragons sourcebooks and other tabletop role-playing properties, which gives his children's-book maps a serious world-building credibility. His role on the books in this corpus is map illustrator rather than interior or cover artist. Niche by definition, but a meaningful signal of the world-building investment behind the series his maps appear in.
