When MJ Quijada, a street-smart Filipino-American teen, embarks on a summer getaway to the Philippines, he expects beaches, family reunions, and a much-needed break. Instead, he and his closest friends stumble upon a forbidden artifact-a piece of mystical hemp paper that shatters time itself.
In the blink of an eye, they are hurled thousands of years into the past-to an era of warriors, mystics, and empires on the brink of war. Now, trapped in Ancient China, MJ and his crew must navigate a world of warlords, assassins, and ancient prophecies, where one wrong move could alter history forever.
Standing in their way is Cai Lun, a power-hungry warlock who seeks dominion over time itself. With his Book of Life, he raises an army of undead warriors to crush all who oppose him. As the battle for the future rages on, MJ and his friends must forge alliances with legendary warriors-from the fearsome Xiongnu tribes to the disciplined Shaolin monks.
