Koom of the Tillamooks, written by Margaret Watt Edwards and illustrated by Roger Cooke, is a historical fiction story aimed at middle-grade readers. The narrative centers on the title character, Koom, who finds himself unable to remain with the last few surviving Tillamook Native Americans living along Oregon's Tillamook Bay. Feeling equally alienated and uncomfortable in the encroaching white man's world, Koom makes the difficult decision to forge his own path. The plot follows his journey as he prepares to isolate himself and spend the upcoming winter surviving entirely off the land.
