When a violent storm pulls young Mira beneath the waves, she awakens in a hidden world—an ancient underwater kingdom shimmering with coral towers and secrets older than time. There, she learns she is the last of the Tidecallers, a bloodline bound to the ocean's will and to a chained serpent god named Thalor. As shadows from the Abyss rise to reclaim the deep, Mira must uncover the truth buried in her soul: that she once sealed Thalor away to save the world—and may be the only one who can free him without destroying it. Torn between duty, destiny, and compassion, Mira's choice will decide the fate of both sea and shore. Beautifully written and hauntingly atmospheric, The Kingdom Beneath the Sea is a story of memory, sacrifice, and the power of a single voice to calm even the wildest tide.
