Woven masterfully into this book are a number of compelling sci-fi features and themes that not only move the plot forward, but unlock the reader’s imagination, inviting contemplation and reflection. As the narrative unfolds, we are pulled into the lives of a cage fighter, Kaev, who is paid by his mob boss and lover to throw his fights, a city bureaucrat, Ankit, who is searching for a way to free her institutionalized mother, a teenage gender-nonbinary courier, Soq, sick with “the breaks,” trying to find a way to get by, and Fill, the wealthy son of a mega-rich power-broker, all against a backdrop of powerful people maneuvering to keep power, and those less fortunate maneuvering to survive. We meet her again about half-way through the novel, and, eventually learn that she’s there to find her long separated children and spouse.

The plot kicks off when a mysterious woman-the orcamancer-rides an orca to the city, polar bear at her side, triggering rumors and speculation about who she might be, and why she had come. Themes like hybridity and diaspora, alienation and found family, greed, religious intolerance and genocide, class struggle, revenge, and rebellion are all seamlessly woven together in a tale told in the floating Arctic city of Qaanaaq, a city peopled with refugees, run by artificial intelligence, and owned by the mega-wealthy. Miller creates a vivid, if daunting and dystopian, future after climate change has so ravaged the world that the great powers have fallen and nearly everyone is a refugee.
