Aimee Ibrahim was the target of political terrorists in The Hidden. Now she's on the run in wartime Europe, determined to avenge those who got away with murder. Her exit from Egypt is fraught with danger and her two travelling companions - Pierre Rigaud, a French academic and Adem Ediz, a Turkish mathematician - are both acting very suspiciously. While on the run news comes in that the Zephyr is on her tail. He is the last remaining link with her mother Hezba Sultan. Hezba's diary revealed the story of the Zephyr and his men, and why he must be killed no matter what.
