Wild unicorns are dangerous, bloodthirsty and… immortal. A true winged horror. They lose their immortality when they bond with a rider, but at the same time they lose a little of their rage. That's why every year they look for 13-year-old children who can form a bond with a unicorn and channel its magic. After the exam, the chosen ones go to the Nursery Gate to try to open it, find a unicorn egg and become riders.
Actually, this is exactly what Skander Smith has been dreaming about for years. However, on the day of the exam, everything goes terribly wrong. Is the dream over? A mysterious horsewoman helps Skander get a chance - and fortune is on the boy's side again. At least, it seems so. However, soon the dream of unicorns loses its rainbow charm. Skander finds himself on the very edge of a bloody struggle with the sinister and mysterious Weaver. Trying to uncover the secrets of the enemy, the boy realizes that together with his unicorn, he is perhaps the only hope for the Island.
