Invitation to Death

Once upon a time they were the cool kids. The most popular by far in the class of 1999. Then in senior year something terrible happened, a tragedy brought about by their shameful behavior one drunken night. A solemn vow was made to never speak of it and never see each other again after graduation. Now, decades later, they've received invitations to an exclusive Christmas Day event at remote Raven's Reach manor. The lure? A shot at winning a million dollars. Once they're together again, bad things start happening. Is this the past finally catching up to them or something far more sinister?
