The late Heinlein, considered the ``Father of Modern Science Fiction,'' was also a prolific letter writer. Virginia Heinlein, his wife of 40 years, has skillfully organized a selection of his voluminous correspondence. The result is a memoir that will appeal not just to fans, but to anyone interested in the creative process. Heinlein's letters, mostly addressed to his long-time agent, are grouped into topical chapters: ``About Writing Methods and Cutting''; Fan Mail and Other Time Wasters''; and ``Stranger,'' (referring to his novel, Stranger in a Strange Land ). Other chapters cover domestic concerns, travel, etc. Coupled with Virginia Heinlein's commentary, this arrangement helps alleviate the disjointedness often associated with similar compilations. While the book is not autobiographical, it does reveal the psyche of a popular science fiction author. Highly recommended for libraries from high school level on up.-- Gary D.
