Some secrets are worth dying for. Eric Swan has died for plenty of them.

But the woman known only as God Maker isn't just a secret — she's the architect of everything Swan is. She built the technology that allows his consciousness to be transferred between bodies. She is the reason Q2's invested agents exist. And now she's been kidnapped.

Her captor is a ghost: a former Q2 operative who vanished six years ago and has resurfaced with a plan that could weaponize the investment program itself. If he succeeds, the technology that keeps Swan alive could be turned into something far darker.

Swan is hunting a man who knows exactly how the program works — and exactly how to use that knowledge against him. And beneath the urgency of the case runs a quieter dread: what if the version of himself chasing this down isn't quite the real Eric Swan anymore?

God Maker is the third book in the Eric Swan series, and the most personal case yet.
