This is your generic ghost/haunted house story with a subplot dealing with capitalism and corporate greed which is something I can say I've never read in children's horror before. The titular Gravemother is suitably creepy and there is good description around her physical appearance and actions. My main problem here was this comes in at twice the length of a goosebumps book and it really didn't need to be. It's a slow burn bogged down with a ton of filler.
