Lowriders to the Center of the Earth by Cathy Camper

Lots of action here and humor including puns. There are many GN fans who will enjoy the fast pace and adventure. One thing I noticed is the inclusion of Spanish is done in a way that seems like the mix of Spanish and English I experienced in Texas. It reminded me of people who may have English as their first language who had heard Spanish around them frequently. They would mix Spanish words or phrases into English - often for humor. I'm not sure this always reflects well in this text for readers who actually speak Spanish fluently though people with incidental knowledge of Spanish may enjoy catching some of the words they know and learning some new ones. There are definitions included for almost all Spanish words so it seemed this is marketed toward readers who aren't likely to know Spanish.

I don't know if this totally makes sense, but that was what I pondered while I read.
