The Buffalo Hunter Hunter

Vague spoilers included: Stephen Graham Jones creates an absorbing new vampire mythology but in the last play misses the basket/TD/goal/run. The final scene was "meh" with vague motivation and reasoning, and includes a discrepancy with something established earlier in the book. Would the ultimate act accomplish the intended result? Prior incidents in the book suggest perhaps not. The author's afterward suggests 'why' this happened, but the rewritten frame story feels like a rush to publication. 95% great and 5% flat. Unfortunately, the 5% was the ending.
