The Parts We Play (фемслэш)

The Arendelles are just your average, suburban, upper-middle-class white Australian family. In fact, one could be mistaken for thinking they are the perfect family. A husband, a wife, and their two happy children. Just like on the commercials.
Except they’re not perfect. Far from it. They just play their parts far too well.
A life left behind. An innocent family tree project. The house behind the soccer field. A terrible mistake. Years of festering secrets, resentment swallowed down and untold sacrifices. Ghosts of the past threaten to drive two sisters apart, or push them dangerously close together.
