The average person is keeping thirteen secrets at any one time, five of which they’ve never shared with a soul. Secrets can thrill, but they are just as likely to torment; and the deepest ones echo far down the generations. They are private, but they also tell us a great deal about our world.

The Book of Revelations explores the changing nature of the secrets held by three generations of women.

We witness long-buried family secrets shared at last, their keepers set free. Finally, we are forced to wonder whether, after a steady upwards curve, women are once again in danger of being curtailed by censure, caution and fear. But could learning from the secrets of the past help protect our future?
