Cold Moon (A New World #5) – Tonya Coffey

At last the king and queen of Ancients have emerged. Plans are in place for a new world, for all realms to be connected under one decree—an Elemental rule.
Jessa and Micha stand before the kingdom as one, the way it was meant to be. Yet in the distance, a demon lurks, waiting to rip their happiness apart once and for all. Even though they are surrounded by the people they love, who love them, the storm grows. With it, the realization the future may be darker than they planned.
Will Jessa and Micha get their happily ever after or will a demon, from the human world, take the True Power for himself?
