About The Book
A year after Lost Key, James O'Neill wants distance from government work. MI5 officer Sarah Sterling wants the file closed. Neither gets what they want.
Across Western infrastructure, small failures begin to appear. A port disruption. A power fluctuation. A financial anomaly. A system delay no one wants to explain. Each incident looks minor on its own. Together, they form a pattern.
Greywind was built to protect the UK. Fed with Red Team data from classified Key Series exercises, it watches power grids, ports, markets and networks for signs of hostile pressure. It was designed to stay hidden and under control.
Then a Baltic port incident mirrors a scenario that should never have left the room. The question is no longer who is attacking Western infrastructure. The question is how far their own side helped build the weapon.
