Not Recommended, Not Repeatable
It’s almost impossible to write a review without spoilers explaining my stance. So, fair warning: LOTS of spoilers ahead.
This is a book about a neglected child whose only friend is his pet. His parents leave him alone (never taking him with them on their vacations and adventures) with the servants, who are mean to him, and make him do all manner of chores (ones they should, themselves be taking care of).
So… Dillweed plots his revenge (via evil spirits/ghosts) and both of the evil servants are killed (one eats poison that the other was planning on serving to Dillweed, for example).
Afterwards, when his parents come back, he realizes he would be better off without them as well (they try to get rid of Dillweed’s pet) and it’s strongly implied that his parents, also, meet with a terrible end.
While I can see certain adults enjoying this book, it’s definitely not one I want to read to my kids…
