An insatiable, unstoppable beast, the wildfire called
Jackknife has already devoured 17,000 acres of
California's Lassen Volcanic National Park. A devastating
force of nature, it has brought out the very best -- and
worst -- in those sworn to defeat it. Ranger Anna Pigeon
is among the exhausted firefighters, serving as medic and
spike camp security, when an abrupt weather shift sends
Jackknife racing relentlessly in their direction. And 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 rampaging winter storm, Anna
must investigate an inexplicable homicide -- as she and
nine others struggle to survive the terrible rage if
nature. . . and the murderer in their midst.
