I enjoyed the book and found it interesting to read about the characters mainly Sally from 'The Nightmare before Christmas' world as I do enjoy that film. However there were some parts in the book that made me think what such as feel heart beating and bones cracking, Sally is a rag doll so she wouldn't have these things. It was nice to find out that Sally was not the only rag doll and she did have parents. But the whole idea with the different holidays/doors is that they go to the human world. Sally stumbles onto Dream Town and lets the Sandman out when she finally goes to Dream Town her parents say then need to destroy the grove of trees, all the doors including to the human world so the Sandman can't get back. But they are there to help the humans go to sleep so if they destroy the door how can they help the humans go to sleep? They destroy the grove but they bring it back by replanting a sapling from the tree so if it is that easy to bring the doors back what was the point of cutting them down in the first place why couldn't they just block them like it was on the otherside in Halloween Town. Then at the end Sandman just needed a nap and he was fine after! I enjoyed the characters of the book and the pace of the story.
