A fascinating story about time travel under the influence of drugs between 1960s Cornwall and early 14th century in the same places, greatly changed over the intervening centuries. The narrator becomes more and more involved in 14th century life, finally getting confused between details and personalities in that century and his own. It has some shocking consequences, especially the implied final event. Very good, with some of the same air of mystery as Rebecca, albeit very different in many respects. Only slight criticisms are that the characters are a bit cliched and some of the description of the landscape drags a bit. But the author clearly loved her Cornwall.
