Eddie Red Undercover- Myster in Mayan Mexico by Marcia Wells

I read this book aloud to my boys since we had just studied the Mayas.  This book, however, did not include too much about the Mayas (just their gods!).  It was full of action, adventure and humor!
When Eddie's mom travels to Mexico for work, she brings him, his father and Eddie's friend Jonah along.  Their vacation soon turns to an investigation when Eddie's father is accused of taking a Mayan mask from the hotel. 
Eddie and Jonah find themselves involved in a local gang, Las Plumas, and a sweet local girl, Julia.
Points to discuss: Jonah likes Julia -she gives him a kiss on the cheek before he returns to the U.S., gangs, Jonah gives a lot of credibility to the Mayan gods
