This is the fourth book in the Doggerel series.
This time, our hero is in Iceland, determined to discover what is causing all the grumbling and rumbling noises which are coming out of a famous volcano.
With the help of his friend, Gnorman the Gnu, and a new friend called Minnie The Micro Pig, Doggerel solves the mystery, but not without a number of strange and unexpected challenges.
The story illustrations are all done by Mylie Nicholson, a talented young girl who describes her autism as her 'Super-Power!' This is the second Doggerel book she has illustrated and her pictures get better, cleverer and funnier each time. As well as drawing Doggerel, Gnorman and Minnie, she has also created The White Dragon, especially for this story.
