I loved this book. Genuinely spooky and mysterious, often Goosebumps books have an obvious answer to the mystery but this time there were several red herrings that actually played out well - and the actual reveal was done really nicely! Definitely one of my favourite Goosebumps books.

Some of the phrasing felt a little immature, but then I reminded myself it is aimed at people literally 20 years younger than me, lol.
