The Knights Before Christmas by Joan Holub is a wonderful take off from The Night Before Christmas. This book is funny. The knights are trying to stop the invader, Santa. Santa is a determined spirit. He "would conquer their castle", which he did. The knights were pleased with the "bounty' he left.The ending is cute,"Merry Christmas to all, And to all night, knight. This book is perfect for kindergartners through third grade. I was given a copy of this book in exchange for a fair and honest review.
