Lost Laysen is a short novel written by Margaret Mitchell in 1916, when she was 15 and given to her lover, Henry Love Angel. It was published only after 1996 when Angel's son found the manuscript with a number of letters Mitchell had sent him.

It is a triangular love story of love, valor and devotion set on a South Pacific Island.

Upon the death of Margaret Mitchell in 1949, her personal papers, almost all other writing, and even the original typescript of Gone With the Wind were destroyed. Now, sixty years later, the impossible has happened: the world has another story from Margaret Mitchell. A love triangle in the South Pacific is the plot of this recently discovered short novel by the author of Gone with the Wind, written when she was 16 years old. The book also contains intimate letters from the author to Angel. - Publisher.
