It seems Sarah holds the key to unveiling a deadly secret - a plot that implicates unscrupulous mercenaries and crooked politicians, and which goes to the very heart of the Vatican. Sarah has no choice but to run, forced into a ruthless game of cat-and-mouse. She can trust no one, especially when her father's name appears on the incriminating list.

Sarah finds herself at the centre of a world-wide conspiracy its keepers will stop at nothing to protect.
