Operacja Mir

Parker wakes in an unfamiliar reality with no clear way to explain how he got there. The people around him are versions of people he knows, including a Natalia who is not his Natalia, and he finds himself trapped in the life of another version of himself.

As Parker tries to return to his own world, Natasza searches for him across shifting realities. Their paths move through tunnels, layered timelines, and alternate versions of familiar places and people, while the larger world grows increasingly unstable.

The story builds toward escalating disorder, with more revealed about the structure of these worlds but not enough to make everything easy to follow. The book ends with an open continuation feel, leaving room for more of the series.
