About the book

The polar ice is melting. Every day, it gets harder and harder for the polar bears to find food. So the Great Bear grants super powers to a young bear named Hyko, and sends him on a mission to the land of the humans to stop the ice from melting. Hyko must master his new powers, befriend a human family, and get to the bottom of what’s causing the ice to melt... before it’s too late.

Climate change and energy awareness can feel like overwhelming subjects. But this charming story addresses those huge issues on a scale kids can relate to. In the first of further adventures to come, Hyko introduces children to the plight of the polar bears, and teaches them what they can start doing right now, today, to help.
