This is the third short story I've read by Ron Leighton, and I think it's his strongest yet. The character of Ránača is strong and compelling; wracked by self-doubt, yet resolute. As with his other short stories, Beneath a Vengeful Sun hints at a much greater scope, mentioning a panoply of cultures, nations, and snippets of history.
Beneath a Vengeful Sun is a fun adventure, well worth your buck, and another stirring lead-in to Leighton's upcoming (I hope) Shining Lands book.
