Forsten takes a last look at his screen. 'Don't loose them out of your sight, even for a moment. Let them think they are invincible, that we've got no clue', he urges his security team. He watches Alex(15), Max(9), Phoebe(14) and Rosie(16) through the hidden surveillance cameras of the Museum. The Ark is the largest and most glorious 'Museum of the Old Life' in Virtus, a city in the far future. What Forsten doesn't know is that Rosie was born in Cambridge in 1664 and was brought over to the future, to Virtus, in one of the TIME SQUATTERS time travels. Nor does he know that the Time Squatters (XQ) are about to travel back to the Hellenistic Alexandria of the 300 BC, the palace of Rudolf II in Prague (1600), the London Tower (1300), and more, to discover alchemical secrets that would help them uncover secrets hidden in a Kepler's drawing: the Secret of the Cosmographer. In order to succeed they must find out what secret knowledge Isaac Newton, Leibniz, Fermat, Tadeas Hajek, Ramon Llull, Magellan and others shared. It is a hell of a journey they set out on, chased in almost every era, all on their own, trying to save themselves and the World. And the World turns out to be quite a hostile place...
