The compatibility system
Attach the spine
Magnetically connect the spine to any In-Book™ book using the golden connectors on the edge.
The book takes control
The book's microchip activates its own programme: effects, light sequences and audio specific to that title.
Unique experience
Each book has its own sound and light narrative. The spine is just the engine — the story lives in the book.
