Part 3. Exercise
If you want to introduce the fantasy genre to a younger reader, I can't imagine a better starting place than this book. A lot of story is packed into this beginning chapter book. Although some profound issues are raised, I think what will appeal to most young readers is the adventure and the relationship between the boy and the new pet he brings home - which, in this case, happens to be a dragon! Readers will no doubt want to read the rest of the books in this series which, though not as good, are certainly entertaining.
Answer:
Positive
