While we don’t publish the ebooks, we are publishing the print and audio editions of Peter Grant’s Maxwell Saga. STOKE THE FLAMES HIGHER is now available in audiobook; print is coming soon.

Bob Allen narrates the fifth book in the Maxwell Saga, which is 11 hours and 5 minutes long.

Two planets, torn apart by the same fanatics – and Lancastrian forces are caught in the middle! Major Brooks Shelby must keep the peace, on a world where radical terrorists want submission or death. Lieutenant-commander Steve Maxwell must trace the source of their fighters and funding, deal with diplomats, and fend off a nosy journalist.


The marines are up against smuggled explosives and suicidal martyrs, while a suborned bureaucracy stymies the investigation. Brooks and Steve must find a way to stop their enemies at all costs, before the fanatics unleash their own version of Armageddon!


And last, but far from least, is Jeffro Johnson’s APPENDIX N, now available in hardcover. It is 355 pages and $24.99.

APPENDIX N: The Literary History of Dungeons & Dragons is a detailed and comprehensive investigation of the various works of science fiction and fantasy that game designer Gary Gygax declared to be the primary influences on his seminal role-playing game, Dungeons & Dragons. It is a deep intellectual dive into the literature of SF/F’s past that will fascinate any serious role-playing gamer or fan of classic science fiction and fantasy.


Author Jeffro Johnson, an expert role-playing gamer, accomplished Dungeon Master and three-time Hugo Award Finalist, critically reviews all 43 works and authors listed by Gygax in the famous appendix. In doing so, he draws a series of intelligent conclusions about the literary gap between past and present that are surprisingly relevant to current events, not only in the fantastic world of role-playing, but the real world in which the players live.
