Protolan. The Code of Magic

A novice sixteen-year-old programmer Kirill notices a cocoon of shining threads in his own house, from which creatures from another world suddenly attack him. Miraculously, the young man manages to escape and destroy the unknown monster. Then he is invited... to the magical Institute of programming, where they teach how to create code in a special language – Protolan, capable of erecting protective barriers against demonic beings in our reality. Kirill and his friends are not doing well: a practical assignment threatens to turn into death, magical symbols are hidden deep in their own subconscious, and Kirill's mentor turns out to be too attractive for him to concentrate… And how in such a situation could one not get expelled from the Institute?
