For years, Lyra gave everything to three Alpha mates, certain their bond would make her Moonheart Queen. Then, in front of everyone at her coronation, Kael, Ronan, and Finn reject her and call her weak. Humiliated? No—Lyra chooses another path. She unlocks an ancient sea-marriage pact and takes Caspian, the feared King of the Deep, as her new fate. In the depths, she discovers her hidden lunar bloodline, a family bound to her true power, and the strength Moonvale worked so hard to suppress. By the time her old mates regret it, Lyra has become the Lunar Sovereign.
