A woman walks solemnly along the gravel path of a cemetery to visit her husband's grave and other family members.

How was Elizabeth Chapman to know that her husband single-handedly killed the son of the world's number one terrorist leader has triggered an international jihad, one in which her young son has become the target of revenge?

Terrorism soon finds its way to the doorsteps of her English country estate. Her mother is killed, and her son is gravely injured, saved only by the heroic efforts of the responding police, and by Jack Lancaster, the hospital's trauma surgeon.

The terror mastermind doesn't stop there. Determined to take the child's life, he recruits the Viper, a well-known assassin sought by Interpol and governments across Europe and the Middle East for his headline-grabbing acts of terror.

Elizabeth Chapman is instantly propelled into the heady world of international intrigue, as she fights to protect the life of her child by escaping to the United States with Jack and by the unlikeliest of allies, her lifelong, dearest friend from Scotland, Fiona Hunter.

They are being followed, and what soon transpires changes their lives forever.
