* The Three-Body Problem * The Dark Forest * Death's End
Expanded my perception of life, death, love, time and our potential purpose, via some very well written fiction (space opera style). Chixin Liu nailed it!
If you can, read it without any previous info - there are big spoilers in almost every description of the book.
I am now reading Revelation Space.
Do you have any book suggestions like the Three Body Problem? What I liked about it was the attention to detail to science and the fact that it was recently written meaning most of the scientific facts stated in the book are not outdated or disproved.
