The White Knight & Black Valentine (Book 0): The Best Man

Harris Holt has one job: to make sure his best friend’s wedding goes smoothly. But when his friend is a retired superhero marrying a former villainess, that involves more than just remembering the rings and making a good speech at the reception. Especially when a guy with a gun turns up at the wedding venue.

Now Harris has to keep a supervillain with a grudge from offing the bride and groom—and keep it quiet, or else the cops will crash the ceremony. With his own rusty superpowers and a murderous maid of honor for help, Harris needs to stop the bad guy before the happy couple gets cold feet…on their corpses.
