Historical fiction, martial arts and romance unite in this epic story of intrigue, good and evil, ancient prophecies and justice. When George Fleener is kidnapped, his teenage children Cage and Mia find a backpack full of his junk-an old-looking notebook, a broken flashlight, a cracked mirror, and a strange metal orb that quickly reveals itself as the key to a time-travel portal. Cage and Mia are transported from present-day Seattle to the Forbidden City of medieval China, where they are captured by the fourteen-year-old Ming emperor. Cage uses his wits and his years of martial arts training to prove their innocence, save the Emperor, evade conspirators and find love. But he has opened a window of evil, and he must solve the riddle of life and death before time runs out.
A 27-year-old cold, calculating assassin from the 21st century. She is deadly, intelligent, but yearns for a more peaceful life. After being betrayed, she transmigrates into the fragile body of Lin Yue, a neglected concubine in the ancient Hanzhou Empire.
A young, powerful emperor with a ruthless streak. Deeply distrusting of women due to palace politics, he finds himself drawn to Lin Yue's unusual resilience and wit.
