THE KING OF MUD & GRASS is the third book in The Dragon Stone series of novels for middle school readers, following THE DRAGON STONE and A CUP OF KINDNESS. The novel continues the adventures of young King Arthur and his loyal dog, Cabal, as Britain experiences the full brunt of the Saxon invasion. The novel focuses on a great siege at an Iron-age hill-fort, which in the novel is called The Barren Down. The outcome of this battle will determine whether the Saxons shall triumph and thus take complete control over the island of Britain; or whether the British forces will be able to withstand the Saxon advances and ultimately repel them. Through the combined efforts and varied abilities of Arthur, Cabal, Merlin, and the enigmatic woman known as Morgan la Fay, the British prove to be formidable adversaries for their dogged attackers.
