The Marked Hosts

She should've let his soul get eaten. Contessa Torain's job was simple. Talk humans out of blowing up her world because of a few rogue Brevia, soul-eaters. A moment of pure insanity leads her to save a child, Asamee Banks. The brat follows her home. He smells like her kind, only different. His existence creates a mystery it's her responsibility to solve. An attack on the humans leads Contessa and her companions to return home but it's empty.
Contessa's family is missing. The dragon-like guardians of the land are dying. She only wants to find her family. The guardians care only about getting another body.
