On her 15th birthday, Y/N wakes up as a six-inch fairy with butterfly wings, forced to leave her human life behind and live in a fairy village that despises her for her human blood—all while her grandparents wage psychological war to "purify" her and a human boy named Leo waits at the forest's edge, refusing to let her go. Trapped between two worlds that both see her as a monster, Y/N must survive 15 years of fairy cruelty without losing the human heart that makes her who she is—or risk becoming the very evil they accuse her of being.
