When Krista Denton meets Dirk Roeder in Wurzburg, Germany in 1936 she is horrified to realise that he is her Key, the one man she can love enough to bring her back to painful and exhilarating life. When he nearly dies she has no choice but to take him home to New Atlantis, her utopian future world. Because, now that she has found her Key, their lives are inextricably connected. If he dies, so will she. But New Atlantis is no place for a Gestapo agent, and there are those in the city who have suffered at the hands of the Nazi's. Those people want Dirk gone, one way or another. Is Krista willing to risk everything for a man others despise?
