Query: You'll need a dictionary to get through this book!

I made the mistake of taking this book with me on an airplane... without a Spanish-English dictionary! There were words in Lesson One that I couldn't translate. There's no glossery so you're on your own.This book could have been made so much better by adding more definitions and explanations.This is definitely not a beginner's book, and the typos make me wonder how much of the Spanish instruction might be incorrect.
