Book Three The Moons of Pohjola - TUONI - John Bailey

The third moon is the most beautiful. It is also the place where the full weight of two books of choices finally lands.

Tuoni from orbit looks like somewhere a person would want to live. Gold-green grasslands, mountain ranges, three great lake systems, a university, a covered market. Nine thousand residents, nine years of colonial life. The ISC team has never faced a settlement with this much to lose - and has never had a harder time believing it was chosen deliberately.

The Caduceus debris entered the atmosphere at impact and has been circulating for eight months. The V-119 isotope does not damage tissue here. It dissolves coherence. The dematerialization is invisible in its early stages - a shadow that softens at the edges, extremities that become slightly translucent in certain light - until the moment it is not. The fully dematerialized are not dead. They are in the air above Tuoni: present, aware, transmitting coherent signal through an atmospheric carrier medium, waiting for physics to do what physics will do and the eighteen-month half-life to thin the medium enough for reconsolidation to become possible. Theoretically. There are eleven of them when the Sampo arrives.

Dr. Cord Valen's team must work four problems simultaneously: the dematerialization science, which requires building a signal receiver capable of interpreting consciousness distributed into atmospheric medium; the institutional case, which requires building a criminal file against the people responsible for three moons of catastrophe before the ISC commissioner dispatched to manage the liability can suppress it; the fractures within the team itself, including the truth that terraformer Takeshi Oru has been carrying since before the first moon; and the question of what justice can possibly look like when the decision that caused the disaster was made by the woman who also built the settlement it damaged.

Told partly through the eyes of Yuki Tamura - twenty-two years old, grew up on Tuoni, her father's shadow wrong for five months before she told anyone - Tuoni is the trilogy's full reckoning: the grandest in scope, the highest in human cost, and the most insistent on the difference between justice delivered and justice sufficient.

It ends, fourteen months after the Sampo departs, with a young woman at a signal receiver, listening for her father in the air, learning to be patient with the people she loves.

Tuoni is the conclusion of The Moons of Pohjola. Kuutar (Book 1) and Päivätär (Book 2) should be read first.
