Celeste Garrett has finally found a happy balance in her life as the Chosen One, thanks in large part to a certain hunky Irishman. But if there's any lesson she should heed since receiving her calling it's that everything can change in the blink of an eye. Soon a terrible new threat, unlike anything she's ever encountered, causes her to make a gut-wrenching choice that will strip her of someone she holds dear.

As much as she'd like to have a pity party for one, there's no time for that now because wedding bells are ringing in Gainesboro! In between dress fittings and rehearsal dinners, Celeste will have to fend off attacking demons and leering pirates. As if the Dark Army wasn't scary enough our heroine is faced with the horrifying trauma of attending a bachelorette party with her mom and watching Grams do Jello shots. Is a walk down the aisle even possible for a member of the Garrett family when the Dark Army is out to destroy them? More importantly, will the Dark Army Glee Club sing at the reception? Raise your glass to the happy couple, and get ready for a wedding...Conduit-style.
