The GROOTERS
What would you do with eighteen lives to try?
Pippi was for children. Harry Potter for teens. The Grooters is the Dream Worlds series for grown-ups.
About the Series
The Grooters is the story of six childhood friends, shaped by very different cultures, whose dreams pull them into alternate worlds where they find keys to love, purpose, and a well-lived life. A science-fiction adventure for adults who want stories that don't just entertain — they invite you to think differently about your own life.
A Universe Still Unfolding
Book 1 sets the scene and launches the multidimensional adventure. Each new volume will carry the Grooters further across worlds, deepening the central questions and bringing them closer to the answers they seek. Every book has its own Visual Companion, soundtrack, and place in the larger story. At least four books are planned.
Book 1 — Out Now
Six kids from broken families. One Pact that could change everything.
Growing up in Geneva, six friends with global roots and extraordinary abilities watched their parents suffer through failing marriages, addiction, and financial ruin. So they made a promise: to find solutions, no matter what it takes.
Twenty-five years later, in 2018, that Pact resurfaces — and sends them on a treasure hunt across continents and Dream Worlds, in search of powerful crystals.
The Visual Companion
Step deeper inside the Grooters universe. Sixty photorealistic images of the people, worlds, and artefacts that bring Book 1 to life — from the harbour of Sydney to the dreams of Moovia and Steamaru.
The Soundtrack
Every Grooters book has a soundtrack — songs woven into the story that you can listen to as you read. The Soundtrack Explainer reveals why each song was chosen, and how music shaped the writing.
The Card Game - Coming Soon
A unique card game is on its way — born from something the Grooters discover in their Dream Worlds, and shaped by the philosophy at the heart of the series. Subscribe to be among the first to play.
The Author
Henrik Hillerström was born in Sydney, raised in international Geneva, and has lived in nine countries since. The Grooters series grew out of a childhood spent among friends whose parents came from every corner of the world — and a lifelong fascination with what lies beneath the surface of ordinary life.
