Beware! It's Friday the 13th: Dragon Slayer's Academy 13

My mom checked this book out at the library and asked me to read it to see if it would be a good fantasy book for my younger brother and sister. I would definately say it's a good story for kids aged seven to ten. The book begins with a group of kids preparing for the princess lasses coming to join DSA (Dragon Slayer's Academy). The kids, mostly lads with the exception of a few commoner lasses, are very excited. Throughout the book you are introduced to the main characters though are not given a lot of information on their backgrounds. However, knowing this is a children's book, I really didn't expect that. Something that might concern the parents, or at least concerned me a little, was how the book portrayed the adults to be cowardly idiots. When it was time to fight an actual dragon, the adults, with the exception of Brother Dave, ran into the school and hid while the children faced the dragon. The headmaster, Mordred, was a greedy fellow and was consumed with a fear of Friday the 13th (where I assume the book gets its title). The fear caused him to act irrationally by making the kids wear such things as lucky bonnets and eels wrapped around their necks for good luck. Mordred's sister, Lobelia, forces the girl's to wear an ugly dress that she believes to be "fabulous" While I would say this is an overall good book for younger kids to read, I would not recomend it to any parents whose child might be thinking they're smarter than the adults in their lives.
