Ringworld by Larry Niven
Louis Wu is very old, and he gets sick of humanity pretty often. So when he receives an offer to go off exploring a new planet called the Ringworld, he signs up along with a Kzin named Speaker-to-Animals, a young girl he falls in love with named Teela Brown, and a member of a long thought lost race called Nessus. They journey to the Ringworld, which is a very interesting place and perhaps a haven from the impending destruction of the Earth.
Niven is very good at the science of science fiction. Truly, his books are very well researched and thought out on that front although some people may find his explanations of the science-y bits to be a bit tedious.
While this is a hard sci-fi book, there are lots of bits of humor scattered throughout the novel which lightens things up considerably. I really liked the three main characters Louis, Speaker-to-Animals, and Nessus. They feel very realistic, and I wish I could talk to them in real life.
This is a great standalone sci-fi novel. It combines great worldbuilding, real science, and some quirky yet real characters. Granted, this is one of those sci-fi books that almost everyone who reads sci-fi has read so it shouldn't come as a surprise that it's good heh~~ I don't suggest reading the sequels though since they pale in comparison.
