Poisoned by silver and given only one month to live, Moon Pack heiress Aria Moon asks Alpha King Kael Nightfang to sever their fated-mate bond after his ninety-ninth public rejection. She wants none of his throne, armies or territory—only five final moonlit farewells before she disappears. Kael dismisses every warning as manipulation until Aria misses the severing ritual, Lunara's final moon mural reveals a silver-blade wound and moon-thread knot, and scent memories expose the healer who restored his shattered wolf core. Following clues through snow forests, ancestral halls and sealed pack records, Kael discovers that Aria was his hidden savior, Lunara, and the Moon Seer whose evidence can clear Moon Pack. By the time he restores her lands, reforms forced-mate rules and surrenders his crown to the Pack Tribunal, Aria's third moon letter has become her final judgment—and permanent exile is the punishment he cannot escape.
