The Power of the Fortrex — Rebecca L. Schmidt

Clay likes to do things by the book -- by the Knights' Code book, to be exact. Clay practices his knightly skills for hours every day. He wants to be the best of the knights! Lance, on the other hand, would much rather play video games than study a book full of rules. He thinks a true knight goes with his gut. Who needs to practice?

One thing's for sure: The other NEXO KNIGHTS team members are sick of them arguing! Can Clay and Lance work together long enough to take down Jestro and his Magma Monsters?
