“Not the light!”
Wonderfully eerie, haunting novel. The rocks with eyes were very creepy.
I’ve looked for Marianne and Mark over the years but never come across a copy. The same with Come Back Lucy by Pamela Sykes, a time slip/ghost story set in the 1970s, which also has a rare sequel, Lucy Beware, that I’ve never tracked down.
I also love Charlotte Sometimes, The Ghosts (also published as The Amazing Mr Blunden), Tom’s Midnight Garden, When Marnie Was There and A Traveller in Time.
