AS FEATURED BY ASSOCIATED PRESS, STREETINSIDER, NEWSBREAK AND AFFILIATES OF CBS, NBC, FOX, and ABC. THREE FRIENDS. AN ANCIENT PORTAL. NO RETURN. Alex, Tilly, and Max never intended to step through an ancient portal. But with no choice, they're hurled into an otherworldly realm with alien skies and strange creatures. Only days later, they find themselves racing through underground catacombs beneath medieval Rome while a violent, dangerous and power-hungry giant of a man named Luigi Romano hunts them with ruthless ambition . It's a breathless chase where high stakes meet quick wits and split-second ingenuity. Can they outsmart their powerful enemy, or can they stay one step ahead by using their very own “future Nobel Prize winner’s” ingenious inventions to buy time to get away? Step through the doorway but be warned, because once you begin, there may be no way back.
