Ahoy there mateys! I picked up the audiobook of this on a whim because I hadn't read anything by the author in ages.  This is a fun book that I would have adored when I was little.  The main character, Max, solves problems using disguises.  His parents are missing and the 12 year old starts growing up in a hurry.  The plot was fun but a little too unbelievable for me older self but has excellent characters.
I won't read the rest of the series though. Arrr!
