Sergei Vasilyevich Lukyanenko is a prominent Russian science fiction and fantasy author, writing in Russian. Born on April 11, 1968, in Karatau, Kazakhstan, Lukyanenko's works are known for their intense action-packed plots intertwined with moral dilemmas about maintaining one's humanity while gaining strength.

He grew up in a family of doctors, with his father as a psychiatrist, his mother working in narcology, and his elder brother as a cardiologist. Lukyanenko graduated from high school with a gold medal and completed his medical degree at the Alma-Ata Medical Institute in 1990, specializing as a therapist. He further pursued specialization in psychiatry, practicing briefly in Almaty before transitioning to a full-time writing career in 1995.

His literary career began with writing "for the drawer" and "for friends," driven by the scarcity and inaccessibility of good science fiction. Lukyanenko cites V. Krapivin, A. and B. Strugatsky, E. Gulyakovsky, C. Dickens, and V. Hugo among his favorite writers, who influenced his early works' poetics.

Lukyanenko is married to Sonya, a candidate of sciences and associate professor, specializing in child psychology. They have two sons, Artemiy and Daniil, and live in Moscow, where they moved in 1997. The family includes a Yorkshire terrier, and Lukyanenko has a passion for cooking and smoking his beloved pipe.

His works have been adapted into films, with Lukyanenko contributing as a screenwriter. He is a prolific writer, usually releasing one to two books per year, alongside numerous critical articles and short stories.
