Ka recounts the adventures of a crow named Dar Oakley, who—nearly two thousand years ago—ventured to the underworld with a young girl and stole the gift of immortality she meant to acquire for her fellow humans. From then, Dar Oakley lives and dies and lives again, crossing from the world of crows (Ka) into the world of humans (Ymr) and back, as the two become more and more the same, broken, place. Reading it felt like slipping into a lucid dream from which you can’t remember all the details, and yet you awaken certain that you experienced something extraordinary. I am already planning a second read.
