Eclipse Syndicate

From publisher blurb: Eclipse Syndicate Four cloned "sisters," each raised by a different master, each with powers derived from a different source. The genius Europa with her battlesuit, silent Callisto and her ninja training, mystic Luna with her supernatural powers, and raging Titan with her lust for battle. Now reunited, they've sworn to stay together, find a cure for their deteriorating bodies, and prove their superiority to everyone!
