The title says it all 2

The title says it all about the content of the book is true. For it is one man on Mars that has to do with the limited resources at its disposal to survive.
But the title does not say anything either, because if you wait introspection scenes of the main character: go your way. Here no longer questioning like "Why I ruined my life?", "If I spell I swear to better take me ...". Not from moment of delirium therefore to solitude.

Here all the force of the narrative is in action: a phrase, an idea, an action. We do not train, we had to cut out to get out of this mess!
The force is also in the science. All available objects are a contribution and diverted from their first use. All NASA's current knowledge of the spatial and Mars exploration are developed.

All events are necessarily entirely plausible but we let completely take perfectly mastered suspense to the end point.
