Nancy Freedman, a novelist whose wide-ranging books include the bestselling “Mrs. Mike,” co-written with her husband, has died. She was 90.

Freedman died Aug. 10 of temporal arteritis, an autoimmune inflammatory disease of the arterial vascular system, at her home in Greenbrae, Calif., said her husband and frequent writing partner, Benedict Freedman.

In a literary career that began in the late 1940s and continued until her death, Freedman wrote or co-wrote 20 novels.

The first was “Mrs. Mike” (1947), the story of a 17-year-old Boston girl coping with living in Canada’s northwest wilderness with her Mountie husband in the early 20th century.

A bestseller that appeared in 27 foreign editions and remains in print, “Mrs. Mike” was turned into a 1949 movie starring Dick Powell and Evelyn Keyes.
