I Hunt Killers by Barry Lyga I saw this is Barnes and noble the other day...looks interesting
The Lost Code (Atlanteans 1) by Kevin Emerson: This book is pretty great. It combines kids that develop gills at summer camp with a dystopian society searching for the lost city of Atlantis. Owen is a fantastic character that you can really cheer for and the author's world-building skills are amazing. Definitely a book for both boys and girls and adults who like a great mystery.
