This came out today:
Inferno (Robert Langdon, #4) by Dan Brown - Reviews, Discussion, Bookclubs, Lists
I'm about ~2 hours into the audiobook and so far it's pretty solid.
Can't wait to start it. I just finished tearing through Deception Point, Digital Fortress (non-Langdon books), and I'm halfway through Angels & Demons now. I'm getting reacquainted with Brown's books before I start Inferno.
I remember Da Vinci Code well enough to skip it. Inferno doesn't seem to be building off anything from The Lost Symbol, right?
