When a tormented man begs 17-year-old Elisabeth London to travel back in time to save his life, she reluctantly agrees. Assuming Scotland is the destination, she ends up in Ancient Rome instead. The good news is she finds the man; now a bold 17-year-old named Aquarius. The bad news is he's an indentured slave, sentenced to death in the arena, and doesn't even know her yet. Elisabeth helps Aquarius escape and becomes an outlaw herself. Armed with her wits and his rock sling, the new friends are on the run from a relentless slave dealer, Rufus Leptis. Elisabeth soon realizes she's not here to save Aquarius from Rufus, but from the doomed city of Pompeii. Although trying to be brave, the thought of remaining in Aquarius' swashbuckling world a minute longer than necessary is inconceivable. At least, it used to be. Before that darn, happy-go-lucky slave stole her heart.
