Long before his death in 1988, Robert A. Heinlein had expressed the desire to have a selection of his letters published, after he was gone, and entitled 'Grumbles from the Grave'.

But increasing pressure from his work and a series of major illnesses made it impossible for him to undertake the job of editing this himself. Now his wife, Virginia Heinlein, has taken on the labor of fulfilling his wish.

A selection of the letters of Robert Heinlein from 1939 to 1970. This collection offers a fascinating glimpse into the mind of one of the most influential science fiction authors of the 20th century.
