Help me find a scene

I had a random memory about a scene from a book. I’m about 90% sure it’s ZA. Scene in my head is - Darcy & Orion have an old book and it needs to be destroyed and Lance has a cute moment when he is such a book nerd that he really doesn’t want to destroy it even though it’s evil? Because it’s old and important?! Okay this sounds really dumb and lame. But you know that feeling when you need to figure out where this random scene it from! Killing me right now.
