Wild unicorns are dangerous, bloodthirsty, and... immortal. A real winged nightmare. They lose their immortality when they bond with a rider, but at the same time they lose a little bit of their fury. 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 the unicorn egg, and become riders.

In fact, this is exactly what Skander Smith has been dreaming of for years. However, on the day of the exam, everything goes terribly wrong. Is the dream over? A mysterious rider 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 at the very edge of a bloody battle with the sinister and mysterious Weaver. As he tries to uncover the enemy's secrets, he realises that he and his unicorn are perhaps the only hope for the Island.
