Grace and Steven "met cute" back near the end of our 44th storyline, "The Sting," and got to know each other very well through the course of our ninth book, Rhapsody. That was before Steven became the new gatekeeper of Hell, though, and before a few other things happened.
Still, we've got two more weeks to this storyline, and it looks like we might actually get to the Big Wedding!
