Ayesha Ryder bears the scars of strife in the Middle East. Now her past is catching up to her as she races to unravel a mystery that spans centuries—and threatens to change the course of history.

As Israeli and Palestinian leaders prepare to make a joint announcement at the Tower of London, an influential scholar is tortured and murdered in his well-appointed home in St.John’s Wood. Academic researcher Ayesha Ryder believes the killing is no coincidence. Sir Evelyn Montagu had unearthed shocking revelations about T. E. Lawrence—the famed Lawrence of Arabia. Could Montagu have been targeted because of his discoveries?

Ryder’s search for answers takes her back to her old life in the Middle East and into a lion’s den of killers and traitors. As she draws the attention of agents from both sides of the conflict, including detectives from Scotland Yard and MI5, Ryder stumbles deeper into Lawrence’s secrets, an astounding case of royal blackmail, even the search for the Bible’s lost Ark of the Covenant.

Every step of the way, the endgame grows more terrifying. But when an attack rocks London, the real players show their hand—and Ayesha Ryder is left holding the final piece of the puzzle.
