What's the Name of That Book??? discussion

I'm making a list of young adult, childrens/middle grade and picture books featuring characters with OCD.
I'm trying to be as comprehensive as possible so the quality of the representation or the book itself don't matter.
The character(s) can be the main character, a side character or even a character that is only referenced once.
I do have quite a long list already but I'm posting here to make sure that there is nothing I have missed.

This previous thread may be helpful!

OCD main character

I mentioned this one in the thread Rainbowheart linked, but: Lock the Doors.
