I love teen fic. I just got finished reading Maximum Ride #2 (James Patterson). It was a suggestion from a friend and I didn't even realize they consider it teen fic untill I read through the critic stuff at the begining. I also like kids books. A Serise Of Unfortunate Events is great. Holes is one of my favorite books EVER! Sometimes I can't wait to have kids to share all my books with.
I'm a big fan of teen/YA, especially fantasy stuff like East by Edith Patou, The Earthsea Trilogy by Ursala LeGuin. I also really like adventure YA like Gary Paulsen's stuff, (Hachet, The River). I've been rereading picture books from my childhood; stuff like Beatrix Potter.
www.gutenberg.org is a great place to read out of print or old editions of all kinds of things. Check it out!
