Isabella lives on a tropical island lost in the ocean. She is the daughter of a cartographer who passed on to her all his knowledge about this corner of the earth. Part of the island is forbidden and jealously guarded by a fire demon - or so the legend goes. Many centuries ago they tried to defeat him, but it didn’t work out. Now, when the peace of their sleepy town is disturbed by the news of the disappearance of a girl and the sudden appearance of terrible monsters, it becomes clear that someone has crossed the ancient border. Now only the dedication and brave heart of Isabella, a girl with ink flowing in her veins and who can read the stars, will help save the island.
