I'm no great expert on this (so don't quote me), but I think the guy's Serbian; at least that is what the Russian edition of his novel The Sky-Locked Atlas claims (on the back cover).

If you liked this, you will also probably enjoy the books of Milorad Pavić, presented in various "forms": as dictionaries, crossword puzzles, tarot-decks, and zodiac primers. His latest novel, I hear, has exactly one hundred different endings (choose one!).

Petrović, of course, is an excellent writer in his own right. The Sky-Locked Atlas is very playful and poetic (I've read it in the Russian translation, but the two languages are related, so I don't think it lost much of its essence by being transcribed in that language).

The Siege of the Saint Salvation Church (or so they translate it into English on Wikipedia) is a 400+ page historical novel and is therefore less experimental than the other books. Many consider this to be his masterpiece, but it's a rough gem, I have to say...

Thank you for mentioning THoGF though--I have never heard of it and will look for it at the library the next time I'm there.
