If you were ever searching for the lost book Heinlein ought to have produced on the art of writing, this is it! Wonderful discussions of writing methods, overcoming blocks, and writing on spec and to order can be found throughout, as well as expert (and still pertinent) commentary on the business of writing. These are the greatest letters of Robert Heinlein, as edited by his wife and philosophical soul-mate, Virginia. And when you’re done gleaning tips on creation from the master, these letters make for a most excellent “director’s commentary” to the Heinlein science fiction masterpieces we’ve come to love so well!
