“The Pillagers’ Guide to Arctic Pianos” By Kendra Langford Shaw; Pantheon Books, 2026; 304 pages; $28. The title alone of this debut novel should alert readers that they’ll be entering a very strange, not easily recognized world. Pillagers? Arctic pianos? From the very beginning, this wildly imaginative story will disorient and entangle those willing to take the ride. Author Kendra Shaw lived in Ketchikan and Sitka as a child and now lives in Billings, Montana, where she serves on the city council.
