Michael Young is convinced his brilliant history thesis will win him a doctorate, a pleasant academic post, a venerable academic publisher and his beloved girlfriend Jane. A historian should know better than to imagine that he can predict the future. Leo Zuckerman is an ageing physicist obsessed with the darkest period in human history, utterly driven by his fanatical hatred of one man. A lover's childish revenge and the breaking of a rotten clasp cause the two men to meet in a blizzard of swirling pages. Pages of history. When they come together nothing — past, present or future — will ever be the same again.
