Nora's twin sister

A resourceful young girl entertains and cares for neighborhood children, then becomes involved with a girl who is revealed to be her twin. Their relationship leads to adventures that include a sea voyage and time in Bermuda, medical trouble and a risky situation requiring rescue. Along the way they face misunderstandings, shifting responsibilities, and family revelations; friends assist by posting letters and following the doctor's orders, and the two girls reconcile their differences and assert their own choices. The narrative balances light domestic scenes with travel, danger, and ultimately the twins' reunion and personal growth.
