Phantom Hearts

Amor, a male omega with an unseen power to alter fate, loves an officer who enforces laws against magic. After a vengeance-driven attack nearly kills his lover at their favorite cafe, Amor awakens in another universe, where the same soulmate is a doctor with an entire shared history. Across five timelines, Amor discovers he alone is shifting between alternate versions of his soulmate, while his first love hunts him as an abomination, misled by the authorities he serves. As the soulmates fight to keep Amor alive, he learns his unstable power may be tied to the fabric of the universe itself.
