A backward land with castles in remote places, connected by tunnels and tracks, with occasional inns where travellers can rest. It seems idyllic, except for competition getting out of hand, and the great energy drain, that threatens every big event, disrupting their settled existence. Can our princelings, budding engineer George, and his twin brother, the thoughtful Fred, solve the mystery of the energy drain? Are the people they meet to be trusted? What is Hugo's secret? Is Prince Lupin really a playboy in disguise, or is he really the most important person in the land? And where, or perhaps the question is when, is the mysterious Castle of Hattan?The first book in the Princelings of the East series introduces the major players in this unique world, and sets the reader many puzzles as he or she keeps up with George and Fred's adventures. It's suitable for confident readers aged ten and upwards.
