Excellent pseudo-historical fantasy. Set in "Carce", which isn't eve a thinly disguised Rome of the Empire period, The Legions of Fire
blends Greco-Roman and Norse mythologies in a heroic fantasy of Apocalypse-averted. I'd just finished [b:Lord of the Isles|252589|Lord of the Isles (Lord of the Isles, #1)|David Drake|http://ecx.images-amazon.com/images/I/515B6B5PRSL._SL75_.jpg|244765], and was disappointed that, for all the great reviews it's received, I didn't find it up to the standards of his SF work. This book certainly meets, if not surpasses, those standards.
