Deva Krall lives in a world of beauty. From the roaring Rhaeadr Falls to the deep, mysterious Ogofau Caves, it is truly a world of beauty. Deva Krall also lives in a world of monsters. Every few weeks, strange, hooded black figures come from nowhere and kidnap one of their people, never to be seen again. When she was small, her twin brother, Bade, was taken, and her heart grew cold. Now she is the next target, but Deva won't go down without a fight. When she learns there are other factors she didn't know about, and that after eleven years her brother may still be alive, nothing can stop her from gaining revenge on the people of the moon.
