"Julie Ridgehaven, who has been attending college in California, is called back to her home in Sydney, Australia, because her fiancé Ron McLaren is lost in the bush. Julie's friend Betz Condon has accompanied her to Australia, and the girls go with members of the Ridgehaven family on an expedition to search for Ron. Also in the party are Aunt Isabelle, who had once promised to marry Dr. George; and Wally Ridgehaven, Julie's cousin, who has become interested in Betz. The women take over the housekeeping duties at the Ridgehaven station in the bush, and the men set out in search of Ron." [Publisher's synopsis]
