The Chaos Code by Justin Richards
The Chaos Code is a Da Vinci Code-type adventure featuring 15-year old Matt and his archaeologist father. Matt is stuck staying with his dad during vacation, but his dad is missing, someone trashed the house and someone or something ambushes Matt. The teen then finds clues that lead him to stay with his Aunt and then to an adventure around the globe looking for a long lost treasure and his father. Decent book, but it dragged in the middle as Richards set up the ending and stereotypical bad guy, so...NAY.
