Grumbles from the Grave

Grumbles from the Grave contains an assortment of bits of writing by Robert Heinlein, edited by his wife Virginia Heinlein, published a year and a half after his death. It begins with a short biography of Robert by Virginia. The bulk of the book consists of excerpts of correspondence from the period from 1939 to 1970, from when he began writing science fiction until the onset of his first major illness. Additionally there is the original postlude to Podkayne of Mars and a discussion of cuts made to Red Planet.

There is much detail here that will interest readers familiar with many of Heinlein's pieces and to people interested in the history of science fiction.
