Sian, troubled by dark dreams and seeking distraction, joins an archaeological dig at Whitby. The abbey's one hundred and ninety-nine steps link the twenty-first century with the ruins of the past and Sian is swept into a mystery involving a long-hidden murder, a fragile manuscript in a bottle and a cast of most peculiar characters. Equal parts historical thriller, romance and ghost story, this is an ingenious literary page-turner and is completely unforgettable.
