I read a book as a school aged kid in the 70’s and I think it was probably published in the 70’s.
The most memorable thing about it was the illustrations. I found them so creepy, I could barely look at them. Kind of like the illustration of Alice in Wonderland when her neck gets stretched by Tenniel.
The picture I remember most clearly was one that was a black and white drawing and the girl is holding a single egg in the kitchen. The perspective is as if she’s holding the egg up to a camera on the ceiling. She has large eyes and looks creepy. Imagine Wednesday from the Addams Family holding the egg.
The plot was about a strange girl who moved next door to the main character – a girl of the same age I think. Probably about my age at the time, 10 or 11. I think the new girl holding the egg had some kind of magical powers. I don’t remember liking the girl, so she wasn’t like a fun Pippi Longstocking character. I think the setting was in the country. Definitely not in the city. The kitchen seems like a farm kitchen in a farm house.
I don’t think this was popular book at all. I think I tried to make my friends read it to see if they found it as creepy as I did, and they declined.
I’m afraid that’s all I’ve got. Thanks in advance!
