"Skillfully written, wonderfully entertaining, and fascinatingly detailed…” —BOOKLIST

Ian Carreg is a charming, canny detective with a career he loves and grown children he adores. He’s come to terms with the death of his beloved wife and he’s looking forward to the birth of his first grandchild. Jemma Henderson, on the other hand, is the beautiful daughter of a famous physicist, a skilled surgeon, and a convicted killer.

When Ian pursues Jemma to Cymry Henge, an ancient stone monument, he is sucked into her escape, and awakes in Roman Britain in the year 60 A.D. Ian and Jemma come face to face with both Celts and Romans, and Ian begins to doubt his own sanity—all he wants is to return home. But as they work together, Ian comes to accept the truth and convinces Jemma to help him foil a plot that could radically alter history.
