If Amy and Dan can't stop the Vespers...the whole world will pay.

The enemy is coming. Are you ready to save the world?
After the mysterious Vespers kidnap a number of Cahills, they order Amy and Dan to steal a priceless painting in exchange for the hostages. The siblings then rush to Italy where they arrange a heist that rivals the most famous art thefts in history. There's just one problem-the painting they steal is a fake. With the clock ticking, Amy and Dan have to track down the real painting before one of the Cahill hostages is lost forever.
