Sword in Time

DaVinci has a job to do: travel back in time to save her house from demolition, which isn't a problem except that in doing so, she ruins everything else in her life. Quintus, a hunk from 53 BC stuck in this century, has his own job: deliver a letter from Caesar to Pompey. Obviously, he'll need a time machine, too. But when he and DaVinci accidentally travel together to ancient Rome, they'll both need swords, daggers, benches, and-oh, yeah-a not-broken time machine to get out of there alive.
