Alex Verus can see the future. But he never thought he'd see this day.

Manoeuvred by forces beyond his control, the probability mage has made a terrible choice: he's agreed to work for his old master once more.

Richard Drakh, the sadistic dark mage Alex escaped as an apprentice, has him in his clutches again. And this time, he won't let go so easily.
