Firestorm
(Book)

An insatiable, unstoppable wildfire called Jackknife has already devoured 17,000 acres of California's Lassen Volcanic National Park. Ranger Anna Pigeon is among the firefighters, serving as medic and spike camp security when an abrupt weather shift sends Jackknife racing relentlessly in their direction. When the monstrous blaze has passed, Anna emerges from her protective shelter to discover two men are dead: one a victim of the hungry flames, the other stabbed through the heart. Now, trapped in a nightmarish landscape of snow and ash, cut off from rescue by a winter storm, Anna must investigate an inexplicable homicide as she and nine others struggle to survive the terrible rage of nature and the murderer in their midst.
