Olympia Soirée

Her entire clan wiped out years ago, Olympia has been isolated for much of her life. Now she must travel to Tenguu Island – the only person who can perform a ritual that will restore the sun to a land enveloped in darkness. The heads of each district there (Red, Blue, Yellow) lead a society governed by rigid class structures.

Able to travel between the districts, Olympia discovers their wonders and weaknesses. She also finds an entire underground group of shunned “colorless” individuals who she becomes determined to help. If she can find a mate who will help her continue her lineage and save the world before it is destroyed, she will reveal to that special someone her heart and her true name.
