Amaranth's desperate gamble to buy Dham and the Resistance time has paid off: they have the location of the Demon's Gate. But she is now a prisoner of Raulston and the Inquisition, and he will stop at nothing to get the answers he seeks. With her friends dead or scattered, and with no hope of rescue, Amaranth can only hope Dham will be able to make his way to Edinburgh, Scotland and close the Gate before he's discovered.But as one of the last living magicians, Amaranth finds her mission is not yet finished. With the help of friends—old and new—she must draw on skills she didn't even know she had. Pursued by dangerous enemies and surrounded by magic, she will need to sacrifice everything she holds dear if humanity has a hope of surviving.
