It's hard to say... maybe Swan Lake (y'know, the cartoons and stuff)? I've always wanted to be a swan... Maybe Salgari's Il corsaro nero, but it's a YA novel, though I read it as a kid (then again I also read Brontë's Jane Eyre as a kid and I loooved it). :V
Q: Ever wanted to have sex in (on? on top? up? above? idk the right preposition??) a tree? I know I have!
