Sergey Lukyanenko (born in 1968) is one of the most famous modern Russian Science Fiction writers (if not the most famous one). A prolific writer, he has been publishing up to three novels yearly since his debut in 1990, although he has slowed down recently (new releases became annual since 2002). Unlike many other authors, Lukyanenko eschews writing long novel series in favor of duologies and trilogies, in which he develops a particular storyline or setting and then moves on to the next one. Although most of his works fall into "hard" Space Opera (as hard as it gets, in any case), he has also worked in such diverse genres as Urban Fantasy (the Night Watch tetralogy, probably the most famous of his books), Cyberspace (Labyrinth of Reflections trilogy, arguably the second most famous), and
