Query: A treasure trove!

A treasure trove! Amazing historical stuff from the archives of Frank Herbert, letters, rejection slips, missing chapters, alternate endings. Plus the collected Dune short stories written by Brian and Kevin. I particularly enjoyed the unorthodox collaboration of "Spice Planet" -- a science fiction adventure story that Frank Herbert had outline, a prototype version of DUNE. Something in this book for all Dune fans.
