In the second half of the 22nd century, twins Zoe and Zachary Blackstone were born into a world of nightly madness. This year, they've turned seventeen. After failing to make their goal last year, they are determined to make their goal this year. They set out once again, but trying a different route, although the destination is always the White Mountain, which purportedly holds the key to their future sanity. They've grown a lot in a very busy year. Zoe, along with the Amazon Moira, has taken it upon herself to extend the coven's stock of horses, as well as preparing land formerly used as a golf course into grazing land, while Zachary has found love. They are still supported by their family members and others of the coven in the desperate search for a cure to the Night Madness. They again face hundreds of miles over perilous ground in search for a cure. They've added to the ragtag band of characters, and the whole band presses on determinedly, but will they make it in time to beat the snows, a very real danger, threatening their lives, and any hope for any future.
