Starred Review. A deadly virus has spread rapidly across Earth, effectively cutting off wildlife specialist Laura Byrd at her crippled Antarctica research station from the rest of the world. Meanwhile, the planet's dead populate "the city," located on a surreal Earth-like alternate plane, but their afterlives depend on the memories of the living, such as Laura, back on home turf. Forced to cross the frozen tundra, Laura free-associates to keep herself alert; her random memories work to sustain a plethora of people in the city, including her best friend from childhood, a blind man she'd met in the street, her former journalism professor and her parents. Brockmeier (The Truth About Celia) follows all of them with sympathy, from their initial, bewildered arrival in the city to their attempts to construct new lives. He meditates throughout on memory's power and resilience, and gives vivid shape to the city, a place where a giraffe's spots might detach and hover about a street conversationamong denizens. He simultaneously keeps the stakes of Laura's struggle high: as she fights for survival, her parents find a second chance for love—but only if Laura can keep them afloat. Other subplots are equally convincing and reflect on relationships in a beautiful, delicate manner; the book seems to say that, in a way, the virus has already arrived.
