Got this as soon as it came out, since I've enjoyed all of Brown's so far (as well as innumerable knockoffs). It was okay - it gives formulaic a good name since it is well-crafted, but it's better if you don't dwell on the fact that you've seen the same thing before, i.e. the police are after him, there's a nut after him, there's a puzzle to be solved. This books focuses on the history, symbology and rituals of the Masons, and it's as much of a love letter to them as you could possibly imagine. So it's hardly a controversial topic, as in his last couple. But overall a good read - nothing to write home about, but still a good read.
