Former seamstress turned couturier turned spy Sira Quiroga is finally ready to embrace serenity with her British diplomat husband, Marcus, and the upcoming prospect of motherhood. But tranquility proves elusive. Fate has other plans for Sira.

Installed in Jerusalem under the British Mandate, and enmeshed in the murky world of shady operators, political menace, and catastrophic violence, Sira finds her future with Marcus put to the ultimate test. Forced to reinvent herself again, Sira travels to England and adopts a new identity as a journalist dispatched to Spain. But as her skills at cunning duplicity are put into play, the ghosts of her past follow, bent on wreaking havoc in her life.

Moving from turbulent Jerusalem and austere London to Franco's Madrid and colonial Tangier, and peopled with formidable real-life historical figures, Sira cuts an unforgettable path through the danger, stratagems, chaos, and promise of some of the most momentous events of the postwar era.
