Great sympathetic characters when one character died and the crew had a memorial, I cried. Very believable science and plot.

Especially after playing Kerbal Space Program, I loved the hard science. Character development was very good. I dropped a star because the actual alien interaction was disappointing.

Enough science to make the fiction interesting, plausible, and very enjoyable. Even the politics, though fictional, were believable. Loved it.

Great read. Right mix of action, humanity, politics, and science.

Heinlein would have loved it.

Pretty good plotting like a real Sandford book, but without fully developed characters like Lucas Davenport or Virgil Flowers the book remains two dimensional.

I was looking for a book dealing with a "first contact scenario", and all I got was "rocket science". There was little discussion on alien technologies , just rocket science.

I started reading Sci Fi in the late 70's, and have been doing so ever since. Saturn Run is one of the finest I have ever read, right up there at the top 10 list.

One of the better stories I have read in a while.

Waste.
