Seraphina perishes in agony in her former life when her betrothed, the ruthless shark warlord Kael, pins her arms while his manipulative lover Lira drives a venomous crystal into her heart. Opening her eyes back on the ceremonial mate-selection day, Seraphina rejects Kael before the entire ocean nobility, stunning the aquatic courts by choosing Rhys, a playful dragon eel playboy.
Kael fumes with jealousy as Rhys turns out to be a deeply devoted, formidable warrior beneath his charming, flirtatious exterior. When Lira resorts to desperate assassination plots and shoves Seraphina toward a lethal oceanic undertow, Seraphina and Rhys combine their aquatic powers to crush the conspirators and rule the deep sea.
