A time-slip story which turns into a truly fascinating glimpse of life at Haworth on the Yorkshire Moors when the Brontës were teenagers. You really feel you are there with Heather Jane Bell, the unhappy girl who suddenly finds herself in another world. She has never heard of the Brontës, so it is not a form of wish-fulfilment. And the two she gets on best with are Emily, who befriends her, and Patrick Branwell, with whom she falls in love.
Look at that name - Heather Jane Bell - and don't tell me time-travellers can't affect the the time they visit! (But she doesn't manage to save poor Patrick from himself ...)
