This is the second of the Dream Master books by Theresa Breslin, revolving around a boy with a big imagination and the trouble he gets into when he starts to learn to control his dreams with the help of a magical dream master.
Engagingly written, this is meant for late primary school children or mid grade children. There are a couple of bullies, a school trip to Jorvik, and some magical mishaps that make for a great read. What I really like about these books is the protagonist, Cy, who is clearly dyspraxic (although the condition is not named). We see him with all his strengths and weaknesses, so well observed by the author. I felt instantly drawn to him when I read the first of these, and once again the author does an amazing job here.
It is not really a book for adults so my 4 stars is based on what I expect young readers would think of this, and how much I liked reading about a carefully observed dyspraxic protagonist.
