Clarion may be the future queen of Pixie Hollow, but she knows she still has a lot to learn. For starters, she doesn’t know anything about what happens in the Winter Woods, a part of her world no warm-season fairy has ventured into in centuries. That is … until reports of a monster crossing from Winter into Spring begin to emerge. But instead of finding a monster at the edge of Winter, she finds Milori, the young guardian of the Winter Woods. Together, they form an unlikely alliance as they race to save their lands. But as their bond grows into something more, they will discover the hard way the reasons a warm-season fairy and a winter fairy should not be together. The cost of their love could turn out to be just as dangerous as the nightmare monsters that plague Pixie Hollow.
