Sergei Vasilievich Lukyanenko is a science fiction and fantasy author, writing in Russian, and is one of the most popular contemporary Russian science fiction writers. His works often feature intense action-packed plots, interwoven with the moral dilemma of keeping one's humanity while being strong.
Recently his works have been adapted into film productions, for which he wrote the screenplays. He was also a blogger, keeping a blog at LiveJournal, and posting both personal and public information or snippets of a book in progress. His first blog was discontinued on 11 July 2008 after a conflict with readers over the issue of foreign (American) adoptions of Russian children. He started another blog a few days later, promising firmer moderation policies.
