In a world where soulmates are bound from puberty-living, loving, and dying together-everything about them is unlike humans. Blake, Noah, and Aiden have always been inseparable, their bond deeper than words, their loyalty unshakable. But when Aiden begins to experience the rare and dangerous symptoms of longing, everything they've known starts to shift. As emotions unravel and shadows creep in, the trio must confront the truth about their connection-and how far they're willing to go to protect each other. Because in a world where soulmates mean everything, some bonds are tested by fate itself-especially when that bond is tied to a journey far from home, in search of something... or someone... missing.
