Gemma Stone is excited about being invited to participate in this year’s fitness convention at the stately Northlake Manor Hotel. It will be a boon to her fledgling HealthGems company and a great way to spend some quality time with her best friend and business partner Holly.The only glitch in the weekend plan is that when they get there, they discover that the convention center has overbooked – again. Now they have to share their space with aliens, crackpot authors, and the occasional horde of zombies, not to mention the hotel management – three unpleasant siblings who are either crazy or mean.When a four-star general turns up dead in the lobby, the chaos becomes pure madness, especially for Gemma. It seems the general was a con-man, his murderer was ingenious, and the only clue is Gemma’s business card, clutched in his cold, dead hand.
