These books are the reprints of the Mars Diaries, how could I not be ecstatic?
I honestly did not know how much I liked to read until I discovered Oxygen Level Zero at Christmas 2001 or 2002. That was also when I found out that people could read books more than once. I gobbled those books up. I have now read them 7 times through.
There have been a few minor changes in the Robot Wars from the Mars Diaries, but the biggest is making ten books into five, combining two "diaries" into one novel. This was a good move.
Someone (and it might have been SB), once said that 99% of all books are written for those who like to read. I agree. I've only found a few that target those who are reluctant, even though reluctant readers make up something like 80% of the population. These books are some of those few.
(Rick Riordan does a pretty good job, too)
