Great book for what it is. This is an easy reader book written by a well-known excellent children's author who focuses on writing non-fiction. This book is about modern aircraft. The illustrations are high quality photographs.
I would assume the target market would be for boys learning to read who prefer non-fiction to fiction and who like aircraft.
My sons enjoyed this book when they were at this stage in their reading journey.
I also highly recommend the nonfiction, science picture books written by this author for great read-aloud's for children up through age 8.
