Could you please recommend some fiction novels to me?

I really can't, but if you are interested in the genre called "Alternate History", Harry Turtledove has done some good stuff. Not too violent, but some are a bit long. Gordon Dickson has done some good, straight up science fiction. He's done some great fantasy as well, but that's not what you asked for.

Uh oh. I see you asked for fiction, and I read that as science fiction. What general type of novels are you interested in?

Yep, I mean the science fiction about cosmos or time~ I've just seen The Twilight Zone and fell in love with science fiction, so I want to read some novels about it. Thanks for your replying~

A book about Friction? Coming right up:

Yes. None of them would be too violent.

You might enjoy The Life of Pi.

As for Science fiction, you might try Marion Zimmer Bradley's Darkover novels, which she in fact describes as science fantasy. Some of them are long, but the novels of the two "Against the Terrans" series are not that long.

Here is the Wikipedia article on the Darkover novels. (Clickity-click!) If you look down the page you will see the novels of the two "Against the Terrans" series listed. Bradley, in the preface to one of the later editions states that she had based one of her early novels on a short story she had written at age 15 (circa 1945). The "Against the Terrans" series were written from the early 1960s right up to the end of her career--and represent her personal interest in the series. The many, many other novels she wrote about Darkover were responses to the popularity of certain ideas or ages in the "history" of Darkover. In particular, Zimmer Bradely was interested in gender roles, and relations between men and women in a pre-industrial society.

Clearly you haven't read a Stephen King novel or any of the Hunger Games books.
