The categories are:
- A reference to time
- A position of royalty
- A number written in letters
- A forename or names

I'm also going to make it slightly more challenging for myself and overlap it with my Mount TBR Challenge. That means that the five books I read for this challenge have to come from my own shelves. I certainly have enough books to choose from. I don't think it will be too difficult to find some in the right categories. Time to go scour the shelves and see what I can find!
