The Minoan Time Key. Science Fiction - Quantum series, #4

In 1908, on the island of Crete, Greece, Italian archaeologist Luigi Pernier and his team discovered a small clay disc while excavating the almost four-thousand-year-old ruins of the Phaestos Palace, an administrative centre for the Minoan civilization. The spiral message of 242 figures stamped on both sides of the disc has remained undecipherable for over 100 years by the world's top archaeologists and cryptologists.
Also working with the team is Andrew Tucker, a young archaeologist from Canada who stumbles upon a different discovery, an item with incredible mysterious powers that sends him off in a fantastic series of time-twisting adventures involving trouble and forbidden love with a mysterious yet familiar beauty from a millennia-old myth.
