What’s it about?

The story.

After the events of The Witch Boy, Aster is still learning what it means to practise magic openly. But this time the story also follows Ariel, a girl carrying pain and anger that she does not fully understand. As dark magic begins to surface, Aster and his friends have to work out how to help someone who is frightening partly because she is frightened herself. Molly Knox Ostertag expands the world of the first book without losing its emotional clarity, using magic as a way to explore shame, isolation, friendship, and the need to ask for help. The result is still a very readable middle-grade fantasy graphic novel, but with a more layered emotional centre than a simple good-versus-evil adventure.

Why it lands

Why they love it.

Why kids love it

The specific weight is the frightening girl — Ariel carrying anger she doesn't understand, dark magic surfacing around her, Aster and his friends working out that someone scary can be that way because they're scared themselves. The Witch Boy sequel that widens the lens from identity to hidden hurt.

  • Magic powers
  • Being understood finally
  • Making a difference
  • Friendship and belonging
  • Surviving danger

Why parents love it

The Molly Knox Ostertag follow-up — same accessible art and emotional clarity, more layered antagonist, shame and isolation and asking-for-help as the core themes. Best after The Witch Boy. Strong middle-grade fantasy with proper emotional weight.

  • Conversation starter
  • Cultural representation
  • Beautiful illustrations
  • Great writing
