Jinx (Bigtime superhero series) (Volume 3)

Thanks to her unwanted superpower, fashion designer Bella Bulluci may be the luckiest woman in Bigtime, N.Y. But luck can be good or bad, and it seems like just as many embarrassing things happen to Bella as do positive ones. Like when a charity event that Bella plans get crashed by Hangman, a deadly ubervillain who's after a prize sapphire that's on display. Hangman almost succeeds in stealing the jewel for his evil ubervillain boss, Prism, but Bella's luck helps her escape with the sapphire—along with some help from the suave and charming Debonair. Debonair's not an ubervillain, but he's not really a superhero either. Still, Bella can't help but fall for him, despite her personal vow to have as little to do with heroes and villains as possible. But with Hangman and Prism still after the sapphire, Bella's going to need every bit of her luck power just to survive….
