Now, however, Mamleyev's seminal novel Шатуны (Shatuny), written between 1966 and 1968 and first published in samizdat, is available in English as The Sublimes from Haute Culture Books in Sweden, either in printed and hand-bound form for €2,000 (!) or (rather more usefully) as a free pdf download.
The publisher's blurb says:
In its search for the Absolute and with all its insanity, Mamleyev’s world reminds us of that of Dostoyevsky, but his characters go beyond ethical problems – they look into the abyss, they recoil and admit the existence of superior powers. Mamleyev goes one step further in trying to comprehend evil and metaphysical planes of consciousness. In The Sublimes, Mamleyev’s figures are mystics, perverse occultists, philosophical fanatics in search of immortality, of their own “eternal ego” and of the great Absolute. They sometimes seek evidential proof of the presence of God and the continuation of life in order to find an answer to the most terrifying question: What will they meet with on the other side of death?
