The powerful new timeslip novel from the worldwide bestselling author of Lady in Hay, in which the fate of a young woman becomes entwined with the extraordinary history of a Celtic princess. Jess, a young teacher in London, is attacked by someone she fears knows her well. Fleeing to her sister's house in the Welsh borders to recuperate, she is disturbed by the cries of a mysterious child. Two thousand years before, the same valley is the site of a great battle between Caratacus, king of the mighty Catuvellauni tribe, and the invading Romans. The proud king is captured and taken as a prisoner to Rome with his wife and daughter, the princess Eigon. Jess is inexorably drawn to investigate Eigon's story, and as the Welsh cottage is no longer a peaceful sanctuary she determines to visit Rome. There lie the connections that will reveal Eigon's astonishing life - and which threaten to reawaken Jess's own tormentor. Barbara Erskine's ability to weave together the past and the present, shedding light on a real but little-known figure, makes this a tremendous novel of Roman and Celtic history, passion and intrigue.
