A mercenary outcast with a perversion no one cared to think about. A holy leader, who knows her people are on the verge of great upheaval--and who wants to know more about this new tribe of demons. A battle-mother, possibly the greatest battle-mother who ever lived--if the rules of her tribe don't force her into a battle even she can't win. A keeper of the secrets of history who would control the tides of fate--if only she could. A paleobiologist with a terrible sense of humor. They are all revolutionaries, but none of them expected anything like what they're about to experience.
