I didn’t reread this one, but it totally popped into my mind. I got it from those book order catalogs that you would get in school. The other kids would get the sticker posters and the Dynamite magazines, but I would get a shitload of books. Because my parents were good like that. This was one. The sixth grade were having a sleepover (dur) and the main character is anxious about it because she is deathly afraid of the dark and doesn’t want anyone to know about it. Not going is apparently not an option, besides, why miss out on all the fun? She and her best friend go shopping for new pajamas, which they described in detail, which is a requirement for mentioning any clothes in a YA book. And then she goes to the sleepover and does ok, but spends half the night in the bathroom. I know there were other people to help her through it and she triumphs in the end.
I thought the idea of a school sleepover was fantastic, and I got my wish in eight grade when my jr high had an Awake-a-thon, where we all stayed awake for a whole night in the gym for charity. I don’t know whose bright idea that was, it is not really healthy for kids to stay up all night. I remember mostly dancing to Paula Abdul on someone’s boom box to pass the time. I came home and fell asleep in my breakfast, head first, just like on tv.
