This is, again, a book in the series filled with plot holes. If you ignore these, it’s a relatively exciting book for kids to read.
I do sometimes wonder why Zac doesn’t join BIG just to avoid his parents making him go home to do housework as soon as his mission is finished.
Also, I dislike the series making smart people seem uncool.
But hey, my 6-year-old son is enjoying me read the series to him, so I’m thankful for the bonding time.
