This new LEGO(R) Ninjago(TM) reader is based on the hit, animated Cartoon Network show.That's bad news for Cole, Jay, Kai, Zane, and Lloyd. They've fought the Overlord in the real world and in cyberspace. They've battled him as a giant dragon and as a computer virus. But now the Overlord has transformed into the most powerful creature ever to walk Ninjago™-the legendary Golden Master.This time, the Overlord just may be unstoppable. But ninja never quit. They'll do whatever it takes to defeat the Overlord. Will it be enough?
#10 is the third book based on the conclusion of the season "Rebooted." If you're reading in order, after #9, the books skip over several episodes without explaining anything. The ninja's battle against Overlord has taken them to the moon! But don't worry, they're heading home to save Ninjago City. It tells of how Overlord is finally beaten, and Zane's ultimate sacrifice. Great book for kids, but for adults, good luck not crying reading the final pages.
(Parental warning: at the end, a bad guy and a good guy 'die' in this book, via mutual ice explosion, but both later come back to life in the books/TV series. So avoid this if that's too much for your kids, but it went over mine's heads, they either didn't care or just didn't get it. And loved the book anyway).
