Where the tides remember, the past refuses to rest.
After a whirlwind summer in Greece, sisters Katelin and Scarlett Middleton return home to historic Charleston, ready to settle into their old lives, or so they think. Their cousin Celeste, the polished daughter of a diplomat, has come to live with them for the school year, bringing charm, curiosity, and secrets of her own.
But beneath the magnolia-scented air and cobblestone streets of the Holy City, something ancient has begun to stir again. A new gate hums beneath the harbor's depths, its power bleeding through dreams and storm tides. When the Greek boys arrive unexpectedly, Nikos, Dimitri, and Yannis, the fragile peace of Charleston society starts to unravel.
Relationships fracture. Tensions rise. And as thunder gathers over the Lowcountry, the teens must navigate more than homework and high expectations at their prestigious private school. They're racing ghosts of the past, battling historic predators that prowl the marshes, and deciphering cryptic messages hidden in Charleston's church steeples, iron gates, and secret tunnels.
Between shrimp and grits lunches, Sunday socials, and the lingering taste of sweet tea, the girls uncover a legacy of anchors, guardians, and choices that could tip the balance between the living and the lost. When the storm hits, they'll have one chance to open, or seal, the gate beneath the Holy City.
