I'd be curious to hear your opinion on a couple of points. Several reviews I read claimed that Neville depicted all the Irish in a very negative light, all the characters being thugs, criminals, etc, and that the author ignored the root causes of The Troubles that caused the men to do what they had.
I refused to read these books for years, despite high praise, because the covers were so shitty. I read the trilogy earlier this year and really enjoyed it. I've actually moved onto Weeks' next series (which also has shitty cover art and, one book in, isn't quite as good).
