What was your least favorite Goosebumps book? (SPOILERS)

I would say that The Curse of Camp Cold Lake is definitely a strong contender for the worst book in the series. Despite having some AWESOME cover artwork (which is why I read it in the first place) and a really cool part towards the middle in which the main character briefly visits a wintery ghost world, this story isn't very good. Sarah, the protagonist is annoying as hell, the other characters are equally unlikable, and the twist at the end is highly implausible and forced.

The twist being that one of the other campers (Briana) turns out to be a ghost who was murdered last summer despite no one noticing this dead girl returning the next year and the fact that she isn't see through like the other ghost in the story. In fact, she's perfectly visible and constantly interacts with other characters unlike the prior mentioned ghost girl, who only Sarah can see. I realize this was obviously done to hide the surprise ending but it makes no sense. It would have better if the "surprise dead girl" at the end was Janice, and if you read the book you'll probably agree with me.

Also, I really wish we could have seen something like the awesome skeletal face emerging from the lake on the cover in the actual story. I waited the whole book for that. I realize this isn't a valid complaint as there's are several Goosebumps books in which the artwork often has nothing to do with the story within but it's just so disappointing when one of the coolest pictures I've ever seen does little to represent what the book itself is actually about.

Anyway, what's your least favorite book in the series? Curse of Camp Cold Lake is probably mine.
