So, I unlinked a party member, so the rest wouldn't follow him in. Have the person walk up to the door and pick the lock. After that, you'll likely have the torches lit on either side. Have a different character put the flames out, then walk inside with the first character to take the book. I'm pretty sure if nobody else steps on the plate that lights them, you can open the gate and get back out without getting fireballed.
