We look at D5 differently but I get the Saga reference. I tried it and can see the appeal but it's just too far away from my comfort zone, I guess. Copperhead on the other hand has that whole Western vibe running with the sci-fi, and the characters may be more simple and straight forward in their own way but are compelling beyond their outer appearances.
Sounds like a book I need to check out! I enjoy everything I have ever read from Jay Faeber. Secret Identities, Dynamo 5, Noble Causes. The man crafts some excellent stories for sure!
