Just read this with my 6 year old granddaughter. She is now reading The Boggart and the Monster by herself. I read it with my daughter and son, too, a long time ago! The Boggart is much like a child--creative, impetuous, and loveable--and the other children in the book are real. Cooper doesn't let the grown ups interfere too much. My son and I graduated to Cooper's award-winning series, The Dark is Rising, after we finished the Boggart books.
My 8 year old son likes the series. There are some slow moments in the book that bore him a bit but I never get bored reading this to him. The long sentences are beautifully written. I love the way the author writes.
My eight-year-old son loved this book so much he insisted we write a review. He says: "This book is very entertaining and exciting; it has very interesting plot and is funny. The Boggart is back and is up to his tricks again. This book will make you laugh and feel concerned about Nessie's predicament. I would call this hysterical fiction!" (That's a play on historical fiction.) I did walk in on him laughing as he was reading it, and he recommends it to all of his friends.
