Ides of March

Twin fifteen-year-olds, Julia and Billy, are on a dig in Rome with their famous archeologist father when an earthquake sends the twins back in time two thousand years to just days before the assassination of Julius Caesar. In ancient Rome they are befriended by Apollonia, the beautiful daughter of a powerful Roman senator and Caesar ally.

The Ides of March approaches, and only the twins know Caesar will be murdered, along with Apollonia's family and possibly the twins themselves. Billy and Julia have only days to solve the mystery of how to return to the twenty-first century; they must decide to either risk the consequences of changing history by warning Caesar and preventing the assassination, or keep quiet and see their new friends slaughtered and their own lives endangered. Their choice is further complicated when they learn that Caesar himself holds the key to their return and that disaster awaits their father if he opens Caesar's treasure room on the ides if they don't get back in time to warn him.
