My thought exactly so I asked because I needed an advice.

Nightwatch, for example... I liked the books in Russian, but would you say all the Russian is "grammatically correct"?
Russian grammar is tolerant to such things so most of books (good books I'd say ) are written with ... well... acceptable grammar.
Consider - we don't care about the word order neither do we have articles. Prefixes which are being a nightmare to foreigners don't present any problem because Russian native speakers (and writers) use them instinctively. That would have incorrect spelling (an editor's problem) and style remaining. A bad author has a poor vocabulary and constructs simple sentenses so it's very boring to read them.

Ramil, if you like science fiction, start reading Frank Herbert's "Dune" series. Great set of books, well-written, and very good grammar. Stephen King also. I think your level of English is good, and these books are fun to read. These are written in American English. For a British style, then I'd recommend The Harry Potter series. Very well-written, and I learned many British vocabulary words that we never use in America.
For something more literary... try reading anything from William Faulkner, Thomas Pynchon, and Mark Helprin. Helprin's Winter's Tale is well-written, the grammar is excellent, and it's a fun read. American English.
The Lord of the Rings. Tolkien was an English linguist and professor, and these books are written in excellent grammar. British English.
James Joyce's Ulysses. "Joyce" English. Unlike any other English, except perhaps William Faulkner. Joyce was Irish.
William Faulkner's The Sound and the Fury. "Faulkner" English. Faulkner was a Southern American. Very southern!
Joyce and Faulkner are widely considered to be the two best English authors of the 20th century. Yet, they threw "correct" grammar away, and developed their own styles and grammar... called "stream of consciousness". Pure English, their books are considered classics... and yet they broke all the grammar rules. But their books are masterpieces.
Thomas Pynchon's Gravity's Rainbow, Crying of Lot 49, and his others (he's still alive and writing), has developed his own style of English, and also breaks many grammar rules, in a very brilliant and wonderful way. He's probably the best living American author. He is of Joyce and Faulkner.
Thanks Dobry - you're really Добрый An answer I've been waiting for.

My main point was that there is no actual authority, anymore, for what is considered "perfect" or "correct" English. Our best authors have broken, and are still breaking many of the old grammar rules for English, and they are essentially evolving and changing English grammar rules.
There is no standard, or authority for grammar anymore. English has divided into many different directions. And there are grammar changes with these divisions. Australian, British, American and Canadian... and within each of those styles, English branches into further divisions.
That's another question I needed answer to.

P.S. You've forgot to mention a Chinese English. I could curse for a week about it.
