It's a story about young boy (Eric) who by chain of unfortunate events have to spend his vacation pretending to be a girl (Erica). During this crazy week, he will learn that being a girl isn't that bad. The main theme of the story is something I would call mild forced feminization. Protagonist is forced to pretend to be a girl, but there is no humiliation, BDSM or homosexual encounters. There is however the girl named Wendy that will make Erica feel buterflies in her stomach.
