They say the truth has a way of surfacing. For Kyla Marshall, it hits like a tidal wave. Everything she thought she understood about her world, her power, and the people who shaped her existence is about to be rewritten. The plan that has been running silently beneath the surface of her entire life is finally out in the open — and it is bigger, older, and far more dangerous than anything she could have prepared for. The four siblings are united. The board is set. And what comes next will reach further than Hell, further than Earth, further than anything Kyla has ever been asked to face. Old loves will be fought for. Ancient wrongs will be answered. And the people who have been pulling the strings from the very beginning will finally have to step into the light — and reckon with everything they set in motion. Not everyone will make it out the other side unchanged. Not every sacrifice will feel worth it in the moment. And not every ending will look the way anyone imagined. But some things were always going to come to this. Some debts can only ever be paid one way. The final chapter is here. And nothing — above, below, or in between — will ever be the same again.
