The Children of the Ankh

With two pieces of the Rebus of Akhenaten now in his possession and with information he hopes will find a third in North America, and the remaining six where they have long been hidden, Billy, and his crew sail to New York. Arriving a month later he sets out to find Lauder Trompe, who has information vital to his mission. But before the day is done, Tom and Polly fall from a precipitous cliff in the Cave of Tarhuhiawaku and find themselves two-hundred-and-fifty-thousand years in the past, where they meet Gabe, one of the Nanochromes of Nogoback, but more importantly, meet Ethan, Isaac and India from present day Kips Bay, New York, who, unbeknown to them, have been their companions in their quest from almost the beginning.
