This is the diary of an astronaut that gets stranded on Mars in the not-too-distant future. Working from only the limited resources one might realistically expect to find themselves with in such a situation, can he survive long enough to be rescued? It's a provocative question, and the author is ruthless in his presentation of the difficulties. Our hero pushes his knowledge of physics, chemistry, and biology to the limits, but will it be enough? Obviously, there is limited dialogue, but the author nevertheless presents a very readable story with suitable doses of humor, suspense, and tragedy. The apparent rigor in this story makes it readily applicable to real life (should you ever find yourself stranded on Mars). I loved it, and I can't wait for the author's next work.
Some may find the science descriptions a little too in depth but when read with Mark's (the title character)sarcastic humor it all fits in nicely. The ability of Mark to overcome all the problems he is faced with keep the story line moving at a brisk pace.
