Lunaria

A high priestess of a dark god is attempting to break through an enchanted door. The daughter of a light goddess, accompanied by her dedicated companion, is determined to discover why and stop her. Through an identical door, they enter another world with a man searching across worlds for his lost twin brother. The world they find themselves in is where a population flees for safety from the blood-drinker Dark Ones and settles there because the sun never sets. The other side of this world is where the Dark Ones live, cast by a goddess at the end of a great war, and the sun never rises. After the defeat of a demon-backed necromancer, three companions cross into this world in search of that demon. One is determined to destroy him, and another is searching for the love of her life who found himself trapped in this world. The third, who found himself trapped in another world because of the necromancer, is now searching for his people. This third book in the Dragon's Tear Chronicles follows the stories of Amani, Twila, and Devon from book one and Kaida, Sylvian, and Meelay from book two when they join forces to defeat the Dark Ones and search for a cure for a mysterious sickness spreading amongst the Lunarians.
