An ancient cave newly unearthed in Yemen. A scientific research facility in the Norwegian Arctic. A fertile valley, home to an isolated tribe in prehistoric Kenya. In the stand-alone book two of The Children of Sarah series, Dr Eloise Kluft is wrenched from her new-found happiness to join the battle against an emerging biological threat. In a distant era, an ageing shaman must pit her hard hard-earned wisdom and the gifts of her bloodline against the terrifying dangers she has foreseen for her family. Looking to an uncertain future, a hopeful young couple navigate the fraught path to parenthood in a world where little makes sense but the courage to love. The Fire in Their Eyes follows characters first encountered in Bone Lines, as they negotiate life’s risks and joys... and as the heritage of our remarkable human journey is passed along.
