I have been reading books from Murakami Haruki since high school, and he is still my favorite writer.

"author" would be a better word choice than "writer" I think

I believe he is the most popular Japanese writer in Taiwan, but I know his book iss are not for everyone.

Some of my friends said his novel is so boring, b. Basically, in the book, a lonely guy livinges a isolated life, and surreal things happen.

even better way to phrase the second half could be "Basically, it follows a lonely guy who lives an isolated life and all the surreal things that happen to him."

But even if his novels are not your cup of tea, his non-fiction book iss are still worth trying.

Or "Since high school, I have been reading books..."

Some of my friends said his novel is so boring,, 1Q84, was really boring, since it's basically, about a lonely guy living a isolated life, and who has surreal things happen to him.

Thoese things usually happen for no reason, leading toso they have no consequence.

I always told them if you have tried one of his novels and youthey absolutely hated it or found nothing fascinating in it, you doabout one of his novels, they didn't need to give hims other books another try.

His fiction isn't for youbooks (or: style) might not be for them.

This is fine if he's only written one non-fiction book. If he's written more than one, then it's "his non-fiction books are still worth trying."
