I actually still have a lot of my books from childhood, and back when I had an actual bookcase and not just a lot of boxes here and there, I had them out with all my other books. He-Man and Duck Tales were the big two. If you want to talk about actual, like, books I've purchased myself, then probably the Anne of Green Gables series.
05. A book you acquired in some interesting way.
I have about a dozen books on ancient Egypt. A co-worker of my Dad's had them, and was either weeding his book collection or was no longer into Egypt, and my dad mentioned that I love Egypt, so he gave them to me. The coolest one is really, really old. It's like, turn of the 20th century or so - before the discovery of Tutankhamen. There's just a brief paragraph in his entry, and a lot of question marks - it's pretty cool.
06. A book with a story for you, that reminds you of something specific in your life (a person, a place, a time).
The first thing that popped into my head was Dan Simmons' Hyperion Cantos, which I read the summer I lived by myself in Austin. I was just taking a History of Italian Art class that ended after one month (we had it every day like in high school - it was kinda neat), and I interned at Austin City Limits twice a week. It was so hot I rarely left my apartment, and I ended up getting kind of depressed because I just sat in the same two rooms nearly every day. I did read this series for the first time that summer, though. There's a monster in the first two books called the Shrike, and that thing CREEPED ME OUT. There were one or two nights where I woke up and was sure someone (or something?) was in my apartment, as one does.
