Cut Through the Heart (фемслэш)

Arendelle might have been thawed, but Elsa's old anxieties still fester. And with feelings for her sister that threaten to bloom into full-blown incest, she pushes Anna away once more, unwittingly walking into the trap of someone who would use Elsa's powers for their own. Things aren't always as they appear. The heart is a maze not all can escape from.
