What’s it about?
The story.
Flember Island is in grave danger, with the evil Lola threatening its magic flow and the lives of its inhabitants. Dev, the young inventor, and Boja, his lovable giant red robot bear, may be the island's only hope. This fifth book acts as the conclusion to the series, pulling together the friendship, invention, magic and island mythology built across the earlier volumes. The stakes are higher, but the storytelling remains recognisably Jamie Smart: funny, expressive, full of visual energy and paced for children who like pictures as much as prose. The title's golden heart points toward the emotional centre of the series, not just power, but care, loyalty and the wish to restore peace. It is a satisfying final adventure for readers who have followed Dev and Boja from the beginning.
