If its opposite day, it could already be opposite of opposite, which would be confusing. If you find this line puzzling then you might understand why the kids of the New Resistance are able to rattle the Good Company yet again in Priceless.

Lucas Benes faces his greatest challenge yet when he finds a secret message from his mother hidden inside a sunken cargo container. In a near-death scuba diving experience, Lucas and the New Resistance kids learn that Good Company CEO Siba GUnerro--along with her newest and most beautiful Curukians--is planning a massive art heist. Lucas and friends scour the Spanish countryside looking for clues. But to unravel the mysteries of both the robbery and the cryptic message, Lucas must first discover the only thing that is worth more than priceless.
