The first books I remember really enjoying and begging to go to the library to get were Babysitter Club, Nancy Drew, and Sweet Valley High... then moved on to Jane Austen novels ha ha I was such a geek! (still am I suppose) My teachers even made fun of me reading all the time. I was Belle from Beauty and the Beast-my nose always in a book. Poor Eric (my husband) didn't realize he was giving me another obsession when he gave me my Reader.
edit: I totally forgot Encyclopedia Brown!! Good stuff!
