This trilogy definitely ends on a high note that managed to be… I won’t say scary so much as unsettling. I feel unsettled by the story of Harold in particular. 

These were all so fun to reread as an adult and fit perfectly for the holiday! I’m not sure if these would speak to modern kids so much - the jokes are weak (especially in this book) and there’s not as much depth. I can see them all being very unthreatening for reading aloud though so that’s probably the thought process.
