I suppose. I just don't think we need prompts for prompts. At that point you're looking at:
1. NPC reminds you to trade in your 1st book before proceeding.
2. Prompt pops up and asks if you are sure you want to proceed without trading in your first book.
3. Another prompt asks if you are sure that when you said Yes to the last prompt that you meant it for sure.
It just seems unnecessary.
