Zero-Sum Heart is a romantic, fantastical, and eerie coming-of-age story about love. On her eighteenth birthday, our protagonist enters a magical boarding school and makes a monumental decision that completely derails her life. In a twist of fate, a ritual sacrifice grants her everything she ever desired: an adoring faceless crowd, a dangerous new power, and a whirlwind romance that, unfortunately, remains one-sided. Without a heart in her chest, she is left to wonder how—or even if—she can truly love someone back.
