I work at a high school library and am trying to find titles of two books I had read as a young person back in the 70s. Both were probably titles that I had ordered off of the book order form/flyer that the school handed out back in the day where the kids could order really cheap books, like maybe Scholastic or Troll or something similar.

1. This was a ghost story. Something about a young person (a girl, I think) walking down a lane (I think “Lane” might be in the title) and seeing an old cottage type house that sometimes had an old ghost lady (or couple) living there and I think the girl would visit her/them. I don’t think other people saw the ghosts and it appeared to be an abandoned cottage to other people. The girl might not have known that the old lady/couple were ghosts until later on.
2. This was a time travel story about young people and something to do with a big wheel. I don’t know if it was a wagon wheel of a water wheel but the wheel was important and “Wheel” may be in the title. It’s not “Wheel of Time” by Robert Jordan.
