The Thirteenth Oath

Calder Rane has Lena Voss pinned beside a murdered courier when the corpse suddenly opens its eyes and whispers, “Thirteen hours.” Before Lena can run, the black ring she was delivering locks them together—and every wound he inflicts on her appears on his own body. He is the city’s most feared spell officer; she is the hunted street courier he was ordered to execute. Now they share pain, power, and a countdown, forced to trust the one person who could destroy them both. But every thirteen-hour reset steals a piece of their memory, leaves behind another death, and reveals that Calder has already died twelve times. To break the loop, Lena must decide whether to save the man who once hunted her—or let the next reset erase them both forever.
