What’s it about?

The story.

Brian Reyes has always felt a bit different, even before he grew a unicorn horn, met a talking muffin and swallowed the ruler of the Underworld to rescue his best friend. So when a mysterious invitation arrives for a Unicorn-Only Sleepover, Brian hopes these fellow magical creatures might finally help him make sense of his strange new life. But the glitzy party, held in an enchanted castle in the clouds, isn't all it appears to be, and Brian must fend off rising social anxiety, ignore the uneasy feelings in his gut and stay true to himself if he's going to make it through the night. Dave Roman's addictively surreal, full-colour graphic novel for readers of seven and up wraps a genuinely warm story about fitting in, anxiety and trust inside a laugh-out-loud magical mystery. The second book in the acclaimed Unicorn Boy series.

How it works in school.

A confidence-building graphic novel for reluctant readers that also opens gentle conversations about anxiety, fitting in and trusting yourself.

Classroom role

Why kids love it

The idea of a secret unicorn-only sleepover in a cloud castle is irresistible, and Brian's mix of glitter, gut-feelings and rising nerves makes the mystery genuinely gripping while the talking muffin and surreal jokes keep it very funny.

  • Friendship and belonging
  • Being understood finally

Why parents love it

A hugely readable full-colour graphic novel that treats social anxiety and self-trust seriously without ever losing its silliness. A reliable hit for reluctant readers who still want something with real emotional heart.
