Titles I've written about:
Rot & Ruin (2010):
The world-building is excellent, the pacing is great, and the pages practically turn themselves. It's a story about not only making the best of a post-apocalyptic nightmare, but looking through and past it, forward into the future. The action/adventure never detracts from or overshadows the Imura brothers' changing relationship -- really, it highlights it.
Dust & Decay (2011):
It's the same fun mix of zombie apocalypse and samurai western, made even more enjoyable by the fact that Benny doesn't spend the first third of the book being a brat (as he did in the first one).
