It's Spring Break and a trio of California college kids head out, not to the beach but to the mountains of New Mexico, where they plan on a week of snowboarding, beer, and fun. But the instructions to reach their vacation rental are less than precise and it's late and snowy when they arrive at Taos Ski Valley. They're surprised to find an older couple in the cabin they believed to be theirs but hey, Casey Hardwick, the ringleader of the group, is not known for reading directions or getting all the facts. Maybe the place is actually a B&B. They troop inside and are shown to a bedroom.

Days later, Casey's sister is calling the only friend she knows in Taos-Kelly Sweet-hoping to get word to her brother that their mother's condition has worsened and she doesn't have long to live. No one has heard from Casey, and she urgently needs to reach him. Samantha and Kelly are together when the call comes, and the mystery only deepens once they talk to Sheriff Evan Richards. Yes, the family reported the missing boys and he investigated. He found no evidence that they'd ever arrived. His theory is that the boys changed their plans at the last minute and are living it up somewhere else.

But Sam has a bad feeling about it. Without the help of law enforcement, will she and Kelly figure out how the boys disappeared? And can they find the boys and get Casey home before it's too late to see his mother again? Their only clues seem to come from the mysterious book of runes.
