Boston Adventure is the haunting story of a girl in flight from her impoverished childhood. Sonia Marburg, growing up in a village outside Boston, deserted by her father and burdened with an insane mother, dreams that life can hold nothing better than the imagined splendor of Beacon Hill. When she becomes the protégée of a wealthy Bostonian, her dream is achieved, and with it comes the revelation of an empty, decadent society.
