The Wedding (2013)

From publisher blurb:

The Wedding is the brand new setting for Skulduggery, the roleplaying game of verbal fireworks and sudden reversals!

You are guests at the wedding of Emma Blunt and Martin Sharpe, held at the moderately-swanky Elysian Country Club. Emma’s father, Gerald Blunt, owns a processed-cheese empire, Martin’s one of his star biochemists, and an unmistakably cheesy odor hangs over the festivities. When Emma calls the whole thing off in a fit of pique, it’s up to the player characters to ensure the couple are forced back onto the path of happiness.

With unforgettable (and unforgivable) player characters such as Jean-Philippe Cabot, heir to a French goat-cheese empire and ex of the bride, hell-bent on winning her back; Tom Sharpe, the regulation drunken uncle. He rambles. He drones. He drinks. He bores you to tears. And an eccentric, snobbish food critic eying a high-paid consultancy in the father-of-the-bride’s company. Amongst these figures you must find a way to bring the happy couple back together or destroy them completely, it’s up to you.
