Fated

Alex Verus is a diviner who can see the possible futures ahead of him, and he has spent years keeping out of the war between London's Light and Dark mages from behind the counter of a small magic shop in Camden. Then both sides come looking for him.

They want an ancient magical relic opened, and only a diviner can do it. Alex wants to refuse, but his apprentice Luna, a lonely young woman with a curse that brings bad luck to anyone near her, is tied to the relic, and his friend Starbreeze, an air elemental with almost no memory, is caught up in it too.

To protect them he has to move between rival factions that would happily kill him, using nothing but foresight and quick thinking. Fated is the first book in the Alex Verus urban fantasy series.
