A Cold Day for Murder (Kate Shugak Series #1)

It’s December in the Park, and a ranger is missing. It’s no great loss to the rest of the Park rats, they figure he’s stumbled into a snowbank and will re-emerge come breakup, just in time for the ground to thaw and them to bury him. But when the man sent to look for him also disappears, Kate Shugak, ex-investigator for the Anchorage D.A. and Park homesteader, is sent in search of them both.
 
First in the Kate Shugak series.
