Ah man... when I was younger, I read sweet valley, babysitter's club (my dad used to work for the company that published the series, so i got them all for free), saddle club, thoroughbred, and some of the boxcar children.
I like some of the books from the Buffy series... but I didn't really got into them after the Gatekeeper trilogy. Those were really good. And I still love to read the Anne of Green Gables series, and the Emily of New Moon books. And then the One Last Wish series from Lurlene McDaniel... they're kind of cheesy, but good in their own way.
