It really is just a collection of small excerpts wrapped up as a collection of ‘Cosmic Rays‘ or ‘Imaginations‘ from the author‘s mind.
I guess for me, as a hardcore HDM fan, it reintroduced old friends. It was nice trying to figure out which book they would have come from and where they fit into the storyline. Or even if the author wrote them just for this book. It was a nice half an hour while I sat with a coffee. Nothing more. Nothing less.
