First Book in The Invisible Thread Series. In a world where love is not left to chance, the Cupid Society ensures every heart finds its match, except when rules are broken. Xaivian Dufort is a cupid unlike any other. With the rare ability to see souls, he can predict who belongs together... and who resists fate. Nearing the end of his long career, Xaivian is assigned his most challenging case yet: Vienna Lovett, a brilliant, witty, and fiercely independent marketing executive who refuses to surrender to love. Vienna has structured her life with precision: work, routines, and a quiet home with her beloved cat. Love is messy, unpredictable, and she has no interest in either. But a chance encounter with a mysterious investor begins to unsettle everything she believes she knows. As subtle coincidences draw them together, Xaivian is forced to skirt the Society's strict rules, risking his career, and his control, to keep Vienna safe. But every intervention has a cost, and the threads of countless lives begin to unravel as he confronts a truth he never expected: some hearts are worth breaking the rules for. Will Vienna finally surrender to the impossible pull of fate, or will Xaivian's forbidden interference destroy more than just his career?
