Here’s a nice, thoughtful review of Foreign Devils by Allen Stroud, for SF Book Reviews. He says:
“…the world devised by Honor Jacobs is unique and interesting with its developing mythology, technology, demonology and dark magic. There is substantial grit to the writing throughout and Hornor Jacobs does not compromise in his description of events. There are surprising twists and turns, with character’s murdered, kidnapped and tortured as the writer requires. The conclusion of both quests providing revelations in equal measure.
If you’re seeking a gritty steampunk series, which offers interesting characters in an analogous real world setting, you’ll find plenty to like in Hornor Jacobs’ series.”
