This is the second book in the Greenwich Chronicles series. A magical fantasy adventure about the Guardians who look after Time and their outcast neighbours the Wreccas. When something causes Guardian and Human time to be wrenched apart, Old Father Tim must search for the legendary Gemetbur to repair the machine before too much damage is done.
But he is in danger. And so are Tid and Sofi, his grandson and adopted Wrecca granddaughter, who must find him before it is too late. And amidst this crisis, who will be chosen as the next Time Apprentice? It's a long book at almost 400 pages but very readable with wonderfully individual characters. The Wreccas, with their distinctive way of speaking and their repulsive names will delight too.
