pretty good
Format: Hardcover
This book was about the FGTeev family getting shrunk by the glitch when they were on vacation and it is up to Shawn to save them all. I must admit I never watched their videos, and when my friends learned that, they said that I missed out on what would have been a fantastic part of my younger days. The book was pretty good, but I feel like the plot just wasn't as good as some of the previous books' plots. I recommend it to anyone who liked the earlier books.
