What’s it about?

The story.

Callie, Ted, Zara and Nico are more than best friends, they're like family. But since a school prank went badly wrong and left him humiliated, Ted has stopped talking to the rest of the gang. Then Callie, Zara and Nico make a strange discovery: someone has been living in their school, sleeping in the building after everyone has gone home. Determined to find out who, they start to investigate, without Ted. What they don't realise is that the answer lies close to home. Their classmate Billy, the boy behind Ted's embarrassment, has troubles of his own: with his mum away and his dad's work taking him out of town, Billy has been left with a colicky baby, an angry stepsister and nowhere he feels he belongs. Told from the shifting viewpoints of Callie, Ted and Billy, Cath Howe's fourth novel is a beautifully observed story about friendship, family upheaval and how much can go unspoken between people who care about each other.

Why it lands

Why they love it.

Why kids love it

The mystery of a hidden someone sleeping in the school after dark is a brilliant hook, and switching between three narrators means readers piece together the truth before the characters do. The secret den and detective work make it a page-turner with real heart.

  • Being a detective
  • Friendship and belonging
  • Having a secret base

Why parents love it

Howe braids a genuine mystery with a compassionate portrait of a boy quietly struggling at home, showing how easily we misjudge each other. The multiple viewpoints make it a rich prompt for talking about empathy and communication.

  • Conversation starter
  • Great writing
