Anna Orion barely remembers who she is. Her memories have been completely wiped and the only truth she's sure of is that Earth is dying. She finds herself surrounded by different classifications of healers, warriors, blenders, and tracers and is unsure of how she'll fit in to this new society. Stubborn-headed and willful, she is determined to find the answers to questions everyone seems to ignore. The problem is she might just risk jeopardizing the rest of the human race by revealing too much.
