When twenty-two-year-old Olivia is coerced into marriage by the cruel Alistair Sheldon she leaves England for Egypt, his home and the land of her own childhood. Reluctant as she is to go with Alistair, it's in her new home that she finds happiness in surprising places: she is reunited with her long-estranged sister, Clara, and falls - impossibly and illicitly - in love with her husband's boarder, Captain Edward Bertram. Then Clara is abducted from one of the busiest streets in the city. Olivia is told it's thieves after ransom money, but she's convinced there's more to it. As she sets out to discover what's happened to the sister she's only just begun to know, she falls deeper into the shadowy underworld of Alexandria, putting her own life, and her chance at a future with Edward, the only man she's ever loved, at risk. Because, determined as Olivia is to find Clara, there are others who will stop at nothing to conceal what's become of her . . .
