I think every geeky kid has a favourite book or series; something they've read over and over, and retain warm fuzzy feelings for. So, what's yours?
When I was ten years old, I got the first three Redwall books for Christmas. Over the next year, I tore through the entire series up to that point, then reread them over and over. I loved those books so much, I would read them all in esotaric orders; chronologically, by publication, the reverse of those two, in character sets, by theme, whatever. I've probably read them all at least ten times, and my favourites (The Bellmaker/Mariel of Redwall and The Long Patrol) more times than I can count. My earliest forays into the internet for reals were into Redwall fansites.
I recently reread them all to see if I only liked them because I was a stupid kid, and they hold up pretty good to me. The twists are often painfully telegraphed and I'm noticing some wierd moral stuff I didn't see before, but I could definately see all the reasons I liked them in the first place, and The Long Patrol was still completely fantastic. In the unlikely event I ever have kids, I am definately passing these books on to them.
