A kingdom fallen. A queen victorious. The return to a past long since abandoned ... With Damian trapped in the Abyss, Nixie ventures to a lost city in search of a powerful artifact known as the Eye of Atlantis. By harnessing its ancient magic, she may have a chance to undo what was done by Nudd. But the path to the Eye is wrought with danger. Hidden at the bottom of the sea, it remains heavily guarded in the ruins of a forgotten city. Unfathomable creatures stand in her way, yet the true threat may lie with the Fae themselves. It's war the Unseelie Fae want. To protect her family, it's time for Nixie to show them why the water witches are to be feared.
