What if your world forgot you ever existed — but another version of it was waiting?
When elite bodyguard Alex Metschner is erased from reality, he finds himself caught in a web of global conspiracies, quantum experiments, and fractured timelines. Partnered with Lieutenant Hayami Tanaka, a brilliant young soldier with secrets of her own, Alex must navigate collapsing worlds, shifting identities, and the terrifying truth behind the multiverse-spanning network that erased him.

From the ghost towns of Western Australia to alternate Earths gripped by nuclear brinkmanship, Ivan Ertlov delivers a heart-pounding, thought-provoking ride where nothing is stable — not even your sense of self.
