Ashley and Alexander come face to face with Volterix, the terrifying Thief of Souls – a druid with powers to stop time and change the future of the world. With Alexander's soul, and Paul as his puppet, the druid hopes he can stop the Roman legions from conquering Europe and thus save the druids from extinction. But Ashley knows that will not happen without the mysterious Time-Senders erasing all their lives. In order to save herself, her children, and the man she loves, she has to somehow get Alexander's soul back and find the druid's lair.
