Firefight (The Reckoners, #2)

Rollicking. There's not a lot of depth here, although David is making a case for some of his crazy theories, and there's a glimpse of a larger pattern showing through, true to Sanderson's form.
The metaphors, when attention is brought to them by David, are terrible and annoying. When he doesn't point out how terrible they are, they can be a bit amusing. As before, the David-Megan interactions steal the show.
Entertaining.
