The idea is simple, a computer programmer is thrust into a world where magic is real, and behaves a lot like a computer program.
The idea sounded like a bad D&D campaign when I first heard it, but on the recommendation of slashdot.org, I dropped my $6.50 for the paperback and gave it a shot.
I was very pleased with the results. While the development of things between the lead character and his love interest were predictable, the overall story was fun and well written. Full of interesting ideas, actual character development and plenty of Geek friendly jokes I enjoyed it from beginning to end.
I also liked the fact that the lead character didn't simply become an uber magician who couldn't be stopped. As a matter of fact, he needs quite a bit of help from more experienced minds, and in the end he makes his share of serious, even fatal mistakes.
I recommend the series, and thanks to the publisher www.baen.com making several titles available for free online, I can send around the link with impunity, so others can try the books for free.
I love the Internet. (Computers on the other hand, I could do without)
