Sanjeev's dog Jigsaw is missing in the middle of winter in New Jersey. But this tragedy is dwarfed by what happens to him in the Metropolitan Museum of Art. Has he really entered the 6th Century and become the slave to monks traveling the Silk Road to Byzantium - and might they just be murderers? Trouble is even if he figures out how to get out of this, he's got other problems: someone, or something, is coming after him. Part of the answer might be Sara, a girl who contacts him on the net and keeps talking about the Immortals. But who or what are The Three Hares and how can they stop the darkness about to engulf the world?
