I read this book in the late 1980s. It was about a group of children battling a witch. I can only remember vignettes-
- A child having to walk though a dark railway tunnel but was protected from evil by dragging a rowen stick along the tunnel wall
- The witch transforming into or projecting the image of a distressed kitten floating down a river on debris
- The children running to escape but being constantly stopped by trees in their path. They realise it is an illusion and start running straight through the trees.
That’s about all I remember, aside from really enjoying it! I seem to have only read it once, so it was maybe a book at someone’s house I was visiting. I always re-read books voraciously so it was not one of mine or a library book that I could re-borrow.
