While flawed, Dies the Fire (Emberverse Book 1), is one of my favorite post-apocalyptic novels. The same cannot be said for the the sequel.
The Protector's War (Emberverse Book 2) is set 8 or 9 years after The Change re-worked the laws of nature and plunged the earth back to a semi-agrarian existence. While it was nice to spend time with Clan MacKenzie and the Bearkiller Outfit, and I like the new characters from England, the way S.M. Stirling skips back and forth through time as he bounces between the various parties is infuriating. The individual glorious moments that are the strength of this series was outweighed by how hard the story is to follow.
The Protector's War ends on a bit of a cliff-hanger, and I'll probably read A Meeting at Corvallis (Emberverse #3), which finishes the original arc about the early survivors and their nemesis The Protector of Portland, but I don't expect that I'll go much further into the 14+ books in this series any time soon.
