Jack Alston - Lord Hawthorn - would love a nice, safe, comfortable life. He renounced magic after the death of his twin sister. But with the threat of a dangerous ritual risking every magician in Britain, he's drawn reluctantly back into that world.

Now Jack is living in a bizarre puzzle-box of a magical London townhouse, helping its owner Violet track down the final piece of the Last Contract before their enemies can do the same. And to make matters worse, they need the help of writer and thief Alan Ross. Cagey and argumentative, Alan is only in this for the money. He's loud in his hatred of the aristocracy and their unearned power . . . and unfortunately, he happens to be everything that Jack wants in one gorgeous, infuriating package.

When a plot to seize unimaginable magic power comes to a head on Jack's own family estate, Jack, Alan and their allies will become entangled in a night of champagne, secrets and bloody sacrifice - and the foundations of magic in Britain might be torn up by the roots before the end.

A Power Unbound is the spellbinding conclusion to The Last Binding trilogy by Freya Marske.
