Frozen Sun — Stan Jones

The third entry to the Nathan Active series.

State Trooper Nathan Active has long been caught between identities. Born an Inupiat Eskimo but raised in Anchorage by adoptive white parents, he had little knowledge of his heritage before being assigned to the remote Alaskan town of Chukchi. He only realizes how deeply settled into the local rhythm he is when Grace Palmer, a local beauty queen, goes missing. Active mounts a search that will lead him halfway across Alaska -- and give him plenty of time to discover he is in love with Grace. Closing in on the answers, however, he discovers evidence that points to an agonizing conundrum: she is either dead, or she is a cold-blooded killer.
