Fun light-hearted sci-fi. It doesn't aim higher than that but it accomplishes it perfectly. My low rating only reflects that I don't think anyone misses anything if they skip it. But they wouldn't regret reading it either.

It is built from a fantastic batch of components. 1) A colony ship traveling a decade to settle a new planet. 2) The planet is a snowball with hostile life that can bite through steel walls. 3) They fail to grow food and are starving. 4) Mickey's job is to die and be recreated. 5) Every character is a comic on par with The Martian's Mark Watney. 6) Mickey gets accidentally duplicated.

Each of these on their own would be a solid foundation for a story. Combined, they are just a lot of fun!

I'm looking forward to the movie adaptation. I'm hoping they either keep it as light-hearted fun, but it comes off better on film, or they add some ambition and depth and make it all more meaningful.
