France, 1284. Christina - beekeeper, sister of Marguerite, daughter of the heretic and sculptor Giles of Beauvais - struggles to keep a secret.
Chicago, 2001. Christina Carver, volunteer in a forest preserve and daughter of rebel physicist, Dr Giles Carver, also keeps a secret, even from her sister Maggie.
When a bell rings for matins - when a telephone rings in the middle of the night - Christina will fail to wake and all six lives will change for ever. Each will be forced to confront what is real and what is not in a world that is precarious, relative and unrelentingly mysterious.
