Dmitrii Bykov won the 2011 National Bestseller Award (NatsBest) for his novel Остромов, или Ученик чародея (Ostromov, or the Sorcerer’s Apprentice). Bykov is a repeat winner of the NatBest: he won in 2006 for Boris Pasternak. Ostromov is the final book of a trilogy, following Оправдание (Justification) and Орфография (Orthography). Ozon.ru’s listing for all three novels in one volume, which weighs in at 992 pages and 1345 grams, includes brief descriptions.
Update, June 6, 2011: Given Dmitrii Bykov's high public profile, I wondered how long this would take... Lenta.ru reports that Vadim Levental', chair of the NatsBest Organizational Committee, expressed his dissatisfaction with Bykov's win. My summary: Levental' said Bykov is already well-known and widely read therefore doesn't fit the award's goal of finding a book with unrealized potential to become an intellectual bestseller. Prochtenie.ru shows jury voting tied at two each for Bykov and Figl'-Migl', leaving jury chair Kseniia Sobchak to cast the deciding vote. She voted for Bykov but expressed her preference for Mikhail Elizarov's Мультики ('Toons), which won one jury vote.
