New Year's Eve, 2019. It was Stefanie Anders' celebration party that started it all, and she wished she'd gone night skiing instead. But she and five others opened up a portal into another dimension. They've been branded with triangular marks on their forearms, and have visited landscapes built by their fond dreams and terrible nightmares. Except Stefanie. Now it's her turn. And the ruthless sect of black-cloaked Shifters have ramped their efforts into high gear. For this is their final chance to capture and exploit a Mainworlder. This time, Stefanie and the others must work together to survive the most deadly landscape yet-one that disintegrates before their very eyes. If they fail and one of them dies, none of them will return to the real world.
