My husband and two kiddos read this one, over a series of weeks, at bedtime, and LOVED it! (Yes, we still do bedtime stories --on the couch, every night -- for our kiddos.)
It's fast-paced, my family speculated about the bad guy before he was revealed (and got it wrong!), and we thoroughly enjoyed the QR codes. We've put Deron Hicks' other two books on hold at the library!
