Blackberry wine - Joanne Harris

Everyday magic, he called it. The transformation of base matter into the stuff of dreams. Layman's alchemy.Jay Mackintosh is trapped by memory in the old familiar landscapes of his childhood, more enticing than the present, and to which he longs to return.

A bottle of home-brewed wine left to him by a long-vanished friend seems to provide both the key to an old mystery and a doorway into another world. As the unusual properties of the strange brew take effect, Jay escapes to a derelict farmhouse in the French village of Lansquenet, where a ghost from the past waits to confront him, and the reclusive Marise - haunted, lovely and dangerous - hides a terrible secret behind her closed shutters. Between them, a mysterious chemistry. Or could it be magic?
