Secrets of the Sword 2 (Death Before Dragons, Band 8)

For ten years, I've been using a magical sword that I won in battle to ruthlessly slay enemies, break evil artifacts, and open stubborn pickle jars, but I don't know much about it. That's about to change. Thanks to the fact that I'm dating a powerful dragon, I can get a ride to the dwarven home world, and we're going to research the sword's roots. Not that I care much about its history, mind you, but several allies and enemies have suggested it can do a lot more than whack things. Considering the magical bad guys I fight are always stronger, faster, and more powerful than I am, I need every advantage I can get. There's just one problem: a half-dwarf thief has shown up and says she's the rightful heir to the sword. I want to believe it's a scam and can't possibly be true, but I didn't get the sword in the most legitimate manner. If I have to give it up, I might not be able to do my job anymore, and just as bad, I'll be a target for all the bad guys who have been waiting for an opportunity to take me down.
