About The Book
James O'Neill and Sarah Sterling are not finished. The Ghost Key brings The Key Series to its conclusion.
Something buried deep inside the operation that started with Lost Key has survived. It has been patient. It has been watching. Now it is moving again.
The threat is not a foreign state. It is not a rogue actor. It is something closer, built from the same materials as the institutions designed to stop it.
The Ghost Key is written for readers who have followed the stolen GCHQ drive, the rise of Greywind and the quiet pressure placed against Western infrastructure. Read The Lost Key and The Grey Wind first to get the full series arc.
