I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The heroine's name is definitely Peggy, but the back of the book calls her Catherine. Oops.
I haven't read the book this manga is based on, although I looked at the original description and a few reviews. Not much info - from the sounds of things, it had a fairly strong start but stumbled pretty quickly. Well, even if the story ends up sucking, at least the artwork seems to be decent, if a bit dated looking.
