Emotional devastation, betrayal, strong language, non-graphic violence Celtic Brooch Series — Book Thirteen A Time-Travel Romance of Trust, Betrayal, and the Cost of Knowing the Truth Some truths change history. Others change who you believe you are. Investigative journalist Clay MacIntyre has built his career on uncovering hidden stories and asking questions no one else is willing to ask. When a moonstone brooch comes into his possession, he believes he’s found the story of a lifetime—one that leads him back to the glittering promise of the Pan-American Exposition of 1901, a world poised between innovation and catastrophe. Buffalo dazzles with electric light, optimism, and the illusion of progress. Beneath the spectacle, danger coils quietly, waiting for the moment when certainty falters. As Clay follows a trail of unanswered questions, he is drawn into the orbit of power, ambition, and history at the precise moment when the future of a nation hangs in the balance. When Clay fails to return, Patrick Mallory and members of the MacKlenna Clan follow, knowing too well that fractured time rarely limits its damage to one life. What they encounter is not merely violence or conspiracy—but a revelation that shatters trust, reframes memory, and leaves no one untouched. The betrayal cuts deeper because it is rooted in love. Clay is forced to confront a truth that does not simply add new information—it rewrites the meaning of everything that came before. The people he trusted. The home he believed in. The story he told himself about who he was and where he belonged. There is no easy way forward from here. Understanding offers no comfort, and forgiveness cannot be demanded. The past does not apologize. The future does not explain itself. And identity, once fractured, must be rebuilt—or released. The Moonstone Brooch is a dark, emotionally devastating time-travel romance where belief gives way to reckoning, love survives truth without being unchanged, and the Celtic Brooch saga reaches its most painful—and necessary—breaking point.
