On the remote Manutassi ColonyShip, death is rare. Murder is almost unheard of.

Dr. Miyumi Katahashi, a talented yet troubled physician, never expected to play detective. But when the body of a young woman is discovered floating in one of Inagawa colony’s hydropods, the fragile balance of their isolated society begins to unravel. Assisting Police Chief Whaled Bey, Katahashi soon uncovers far more than just a crime—she unearths buried secrets, illicit affairs, and a power struggle that threatens to tear the community apart.

As the investigation deepens, every answer leads to more questions. Why was Joy Konstantin, a promising young woman with everything ahead of her, brutally murdered? What was she hiding? And what forces are working behind the scenes to ensure the truth stays buried?

Haunted by her own past on the war-torn colony of Regina 4, Katahashi must push through her demons and navigate the treacherous waters of politics, wealth, and deception. But when the killer’s identity is finally revealed, the truth is more chilling than she ever imagined.

In The Silent Currents, the first gripping novel of The Katahashi Chronicles, the line between justice and survival is razor-thin. And in the cold vacuum of space, even the strongest can drown.
