There was a book that I read in the early 1970s about a girl (A) whose family took in another girl (B), I can’t remember why. Girl B turned out to have powers that she used against Girl A. I remember two scenes. Girl A was going to the prom or a big dance with her boyfriend and was going to make her own dress. Girl B “made” Girl A buy a pattern and color for a dress that was unbecoming to Girl A. Also, Girl B “made” Girl A sick right before the dance so Girl B went with Girl A’s boyfriend. I don’t remember how Girl A got rid of Girl B, but the book ends with Girl A saying whenever she reads a story in the newspaper about a wife dying, or an accident with 3 people where the woman dies, that she wonders if it is Girl B is still out there up to her old tricks.
Stump the Bookseller
New format, same book stumper solving.
A possibility: Summer of Fear, by Lois Duncan. Note that these have been updsted, so you’d probably want to look at older editions.
Sounds like “Summer of Fear” by Lois Duncan.
This sounds like Summer of Fear, a Lois Duncan classic.
This is Lois Duncan’s Summer of Fear.
Thank you so much for all the help!
