How Not to Die in the Tower of Mostly Unpleasant Deaths

Neth the swordsman wields a sharp blade. His partner, an enchanted rabbit named Sir Hops-a-Lot, wields a sharp tongue. It's weird, but it works. Usually. But is even their combined strength (Neth), brains (Hops), skill (Neth), wit (Hops), and common sense (neither) enough to survive the patently absurd but unspeakably dangerous Tower of Mostly Unpleasant Deaths? Obviously the answer is yes, because this is a prequel to The Princess That Ate Dragons, but what about the teenage girl who guilt-trips them into this crazy mission? You want to find out if she comes through okay, don't you? Sure, she's a bit rough around the edges, what with the lying and the manipulation and all, but trust us, she's an absolute sweetheart once you get to know her.
Honest.
