I would have gladly used the next book, but at the time, the second book was not out yet and I couldn't wait, so I went with TruthQuest instead. The second book has more grammar in it, and the instructions are in much more detail. I will tell you that do not let the vocabulary words overwelm you. It is not meant for your kids to look up and define every word. Dorian put them in there to show you some words that your kids might not be familiar with and might need some explanation or work with, but not all of them.
