"I have no clue what you're trying to do. However, I am confident you are the one Saphira warned me of when she mentioned someone had stolen the books. I may not know what world you're from, or why you would take these books, but I do know your intentions are not to be trusted, and I am not going to let you just get away with it!"
Raxi shakes his head. "So you intend to fight me after all. What a bother." He opens up his own book, the Book of Mind. "Then I will have to destroy you." He points at you and speaks, "Destruction."
As quickly as you can, you open the book you have out already, which is the Book of the Beast, and say the first spell you see. "Shape!"
The two spells meet halfway between you and Raxi and negate each other.
"So, you've mastered that aspect of the books already. I guess I won't be ending this the easy way."
"You know, there are three of us." Ruby chimes in. "And two of us have books. You can't really expect to win."
"Yes, but only two of you have books. I wonder. How much do you care for your third companion. Would you sacrifice him to defeat me? Or would you loose the opportunity to attack me to save him?"
"John run!" You shout, but it's to late.
Raxi points at John, and speaks the spell word, "Destruction."
