Another great space novel from Andy Weir. Takes the science and the economics of a moon base into account and gives a good story.

Simply a great story.  Keeps the reader glued to the storyline. A plausible look at what the future may hold in the search for a longer life. A good page turner and a recommended read for the sci-fi fan.

I've read a lot of science fiction, and a lot novels that incorporate noir/detective elements.  This was one of the best, and I have already ordered the second novel.  I really enjoyed the setting of a colony world that has become a backwater without access to the highest levels of technology, aware of all that's going on in the galaxy but unable to participate.  This helps set up the feeling of hopelessness that most of the characters share.  There wasn't much in the way of speculative technology involved, the core of the novel was the detective/crime element.  I felt that the ending was out of synch with the pace of the rest of the book, as if Hammond had to fit everything in by an arbitrarily defined page number.  Overall, a good read and I look forward to the rest of the series.

Excellent.  Reading the sequel now. We'll developed science fiction coupled with action action, suspense,  and good character development. Many surprises.

Very good book.  You need not like Star Trek or the TOS characters to like this novel.

The aliens were very interesting.  The ideas speculated about were intriguing.  The setting descriptions were quite nice.  The plot is suspenseful.  Not enough Spock, but still a very satisfying purchase.

I'm glad I bought it.  If you like science fiction and stories about colonialism or thought-provoking questions about time and the origins of species, then you should read this book.  If you like Star Trek, you will like it too.

Wonderful science fiction that keeps you engaged from the moment you start reading it. Asimov's book is a classic of science fiction.
Highly recommend.

This was a well thought, interesting and believable story. The novel was a well told story set in space and on an alien world and in alien ships. It was engrossing. I hope the author turns this into a series and writes new novels involving the main charcters. The action was non stop. The female and male lead were well written, complete people, with details about their past and present. I look forward to the author writing about there future and answering the mysteries of the alien race and its ties to earth.

I enjoyed this book. I  don't read too much science fiction involving space travel. My sister in law told me about the book so I decided to give it a try. The characters and plot lines are interesting. The book takes place in the future. The description of the other world and its people was well written. I enjoyed reading this space adventure so much I am now reading the second book in the series

What a great page turner. Very science-y with lots of technical explanations which I like in a sci fi. Great characters.
