One vow changed everything. All I ever wanted from life as a mermaid was to return to land with Carter. And that’s what we’ve done. Sort of. If only the ocean didn’t whisper my name. If only it didn’t bestow unruly magic upon me. Because now, I must face the wrath of a mighty king who would wash away cities to keep the merpeople secret safe. If I can’t learn to control my ocean-given gift, Carter and I risk losing the most important thing we Our forever.
