The Fractured Self. Signal Drift, #3

The physical and mental walls of the Odin are closing in. As the Great Forgetting tightens its grip, the crew's sense of existence begins to fray at the seams. Dr. Theo Kessler, driven by a desperate need to save his life's work, becomes dangerously obsessed with preserving his own mind, even as his relationships with the crew dissolve into suspicion. Meanwhile, the once-grounded Jax Omari loses his grip on reality as his pragmatic world is swallowed by the impossible.
Caught in the center of the storm, Commander Ayla Rane faces a devastating conflict between her duty as a leader and her love for the people she is losing. Every decision is a gamble with their souls, leading to a crucial choice that will forever alter the trajectory of their future. In the silence of deep space, the question is no longer how to survive the end of the universe, but how to survive themselves.
