Under the Eagle is the first in the Cato and Macro series by Simon Scarrow. I wasn't quite sure whether to classify this as historical fiction or as a historical thriller and put it in the mystery/thriller thread but eventually ended up here. When I first started buying titles in this series in DTB while in the UK on business trips, they were sometimes found in the "crime" (UK-speak for mystery

) section, which is how I found the series to start with, but eventually they moved to either more general fiction, or military fiction if the bookstore was big enough to sort that out. In any case, this is a great series (IMO) that I have enjoyed sharing with my son. (Even giving him nightmares when he was very young about the druids in one of the books...hmmmm...) I think the series is not very well known in the US, but I have the impression it is a big deal in the UK - someone UK-ish could comment, perhaps.
Anyway,
Under the Eagle has dropped to $0.99 at Kindle US and other US retailers. Be careful - there are two versions of this - a Headline version that is the $0.99 one, and a St. Martin's press that is $9.99. You don't want to make that mistake!
