I don’t write reviews much- and I like to normally leave positive ones, but this one is a huge disappointment. My son loves the bad guys series- has every book and I was excited he found a series that got him interested in reading. We were so looking forward to this book for his birthday, and it just wasn’t what we were expecting. It is very different from the rest. It is dark - almost Satan/demonic like. It wasn’t silly or funny like the others. It was hard to follow for a 7 year old and creepy. From the cover art, I was expecting something like Darth Vader like, but it is not. Heads up to parents thinking of purchasing this one- I say skip this one and enjoy the others.
