Book 1: Skander and the Stealing of the Unicorn
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. Trying to uncover the secrets of the enemy, the boy realises that together with his unicorn, he is perhaps the only hope of the Island."

Book 2. Skander and the Ghost Rider
Can an immortal creature be killed? A wild unicorn that lives forever or dies forever? Who is capable of such a thing? And most importantly, why kill wild unicorns? Yes, Skander and his quartet are no longer pupils, they are kids now. But their second year in the Nest begins with the gruesome murder of a wild unicorn. Of course, suspicion immediately falls on Skander, the first clergyman in decades. And the old bard's prophecy adds to the panic, foretelling of evil "born of the power of the spirit."

It's a wonder that anyone would side with Skander, if the most famous family of saddlers or the Peregrine Society, the coolest of the Nest's societies, can be considered "anyone." There are more training sessions ahead, culminating in a jousting tournament for the kids, which will result in the six weakest being kicked out of the Nest. Meanwhile, the wild ones continue to be killed...

Skander and his friends realise that these murders are part of some evil plan. It seems that the Island itself is taking revenge for the destruction of the immortals by devastating natural disasters. Can the quartet of kids stop the deaths? Will they be able to save the Island? And if only they could avoid being expelled from the second year and stay in the Nest for the next year!
