Seventeen-year-old Laurie Reed and her novelist-father have rented a cottage a long island for the summer. Laurie soon makes friends with the regular summer crowd and enjoys a few cookouts and casual dates. Mystery ""washes ashore"" in the form of a Negro girl who has left an orphanage and is living in a cave. The author as written a story which is far too naive for this age group and too old for the power one-- a problem which also existed in Between Home and Horizon (1962, p. 328, J-108), her last novel.
