Aurora

This book hooked me from the very first 20 pages. One of the best generation ship stories I have ever read.

There is such a sense of wonder when the book tries to explore an idea , which is basically impossible to achieve with current technology, while trying to keep the very idea grounded in modern understanding of physics and playing with the speculative tech of the future.

A few thousand people aboard a sentient or semi sentient ship wanting to go far and beyond our solar system to settle and make a new home is the main premise of the book. The plan for them is to terraform one of our neighbor planetary systems (home of the Tau Ceti star) or at least one of the main planet's moon.

All kinds of situation start happening when they find out that things are not going as expected with the biological system of the sentient ship.

I have seen many people disliking the end of the book, but to me it was just excellent. It gave the needed doses of adrenaline and makes you really think about what lies ahead of human exploration and all the risk that comes with it.
