For over 100 years, the Kingdom of Knighton was a peaceful place. That was until The Book of Monsters escaped from his prison! That villainous book is one nasty bad guy (but dont tell him I said so!). Hes stuffed to the spine with page after page of the most fearsome monsters you can imagine. But dont take my word for it! Just look inside to learn all about the vile villains who threaten Knightonand about those pesky NEXO knights who try to stop us!
