7 TAGs, each having 4 prompts, meaning 28 prompts in total. 
Some prompts have more than one option. You can combine them or only choose one.

You can use a book for more than one TAG, but it shouldn't repeat within a group. You can put it to as many prompts as you want though, no one will sue you. But to make it more challenging, use every book only once, so that you have 28 different books in total.

You can still join the challenge after June, but preferably only add those you've also read or started in June 2024.
