Why is Sal in Ohio at the beginning of Walk Two Moons by Sharon Creech?

Sal and her father were from Bybanks, Kentucky, originally. After Sal’s mother left and it is determined that she is not coming back, Sal’s father moved himself and Sal to Euclid, Ohio. Sal resents this move, wanting to stay on their rural farm in Bybanks. The reason for the move is revealed to be Sal’s father's desire to be near Margaret Cadaver, their new next-door neighbor. Sal rejects any kind of friendship that Mrs. Cadaver displays toward her, and willingly joins in Phoebe’s idea that Mrs. Cadaver is a murderer. When Sal spends time with the Winterbottoms, Sal’s father usually goes over to Mrs. Cadaver’s house. Many times Sal’s father tries to explain Mrs. Cadaver’s connection to the family, but Sal refuses to hear it. She resents the fact that Mrs. Cadaver is there and her mother is not.  In the end, Sal learns the connection between Mrs. Cadaver and Sal’s mother and overcomes her resentment.
