The Caesar Secret: Part 2

Desmond and his friends Corin and Diego are psyched about their trip to Rome.
While Desmond's parents, world-famous archeologists, are there for a couple of weeks unveiling their latest museum exhibit, the kids figure they'll see the sights, hang out together, maybe grab some authentic Italian pizza.
But when the kids find an ancient treasure map hidden in Desmond's parents' exhibit, what had been a carefree romp across one of the world's oldest cities quickly turns into the quest of their young lives.
Do the map and the other clues they find hidden along the way really point to a treasure hidden by Emperor Julius Caesar? Is it possible no one has unearthed Caesar's secret stash until now?
Unfortunately, one of the world's sneakiest thieves is determined to find it first. And he's not about to let three brats stand in his way of unimaginable wealth and fame—or of revenge against Desmond's parents.
To outsmart the bad guys, Desmond, Corin, and Diego—now calling themselves the Adventure Guild—must enlist the help of their bodyguards, hired by Desmond's wealthy parents to babysit them in Rome, and draw on their collective knowledge of history and geography to ensure they're the first to discover Caesar's Secret.
