High Quality Content by WIKIPEDIA articles! A Deepness in the Sky is a Hugo Award-winningscience fiction novel by Vernor Vinge. Published in 1999, the novel is a loose prequel (set twenty thousand years earlier) to his earlier novel A Fire Upon the Deep (1992). The title is coined by one of the story's main characters in a debate, in a reference to the hibernating habits of his species and to the vastness of space.
I ended up rather enjoying this book. The beginning of the book had a few changes in perspective that made me worried I wouldn't enjoy it, but the main story stuck with the characters that I found most interesting and by the midpoint in the book I was hooked. My favorite part of this novel was that it did what good science fiction often does: it makes a very believable world that follows easy to understand rules which are not far from our own and then follows a story about what happens in that environment. The story and world that this book postulates was very interesting and a great read.
(Random note: the goodreads page for this book is very bizarre, I problaby just picked the wrong one - the real author is Vernor Vigne.)
All I all, the first one was much better In my opinion, though that leaves a lot of room for greatness. This book has many great moments as well as many endearing characters and interesting plot lines.
