After her mother died a few years ago, Rowena and her sister, Ariana, drifted into their own corners of the world, each figuring out in their own separate ways how to exist in a world in which their mother is no longer alive. When Ariana disappears-- at night, in the middle of a snowstorm-- Row is left to piece together the mystery behind where Ariana went and why. And she comes to realize that she might be part of the reason Ariana is gone. -- adapted from jacket
