The Dead Sea cipher

the long version

It was the start of a grand adventure in a land of antiquity, a rare opportunity to visit biblical places shrouded in mystery. But in a Jerusalem hotel room a world away from everything she knows, Dinah van der Lyn hears angry voices through the wall, followed by a crash and a brief cry in English...for help! The brutal shattering of an evening's stillness becomes a prelude to terror. Without warning, Dinah has been unwittingly pulled into something unholy transpiring in a sacred city, and she must find answers hidden in the shadows. And she must trust an enigmatic stranger as she races through ancient, twisting streets teeming with secrets and peril, a man who may be leading her to safety...or to her doom.
