Colleen Thompson over at Boxing the Octopus interviewed Bev Vincent about this very thing! Bev is the author of The Road to the Dark Tower and The Stephen King Illustrated Companion.
The Dark Tower series spans the majority of King's published career and it was the perfect chance to delve into the literary genius of this incredible man.
The Stephen King Illustrated Companion is chock full of behind the scenes info and family pictures. Want to know what was going on during the writing of each of his novels? Then get this book!
