Mae always thought she was in control, but in the past few weeks, control has turned into chaos. She's learned that her brother, Jamie, has magical powers, and that Gerald, the new leader of the Obsidian Circle, is trying to persuade Jamie to join the magicians. The same magicians who tried to kill Mae and Jamie last month in London. The magicians who get their power by feeding people to demons.
Mae turns to brothers Nick and Alan to help her rescue Jamie, but they are in danger themselves. Every magician in England now knows what Nick really is -- and they all want him dead.
Nick's new power has also caused a rift between the brothers. In the weeks they were gone something terrible happened, something that haunts them both. With Nick as unreadable as ever and Alan making secret bargains with a demon. Mae finds herself attracted to both brothers -- though she knows she can't trust either of them. The magicians are closing in on one side, and the dangerous, seductive Goblin Market is tempting her on the other, and Mae has to form her own plan to save them all. She's going to find that the price she must pay is more than she ever imagined.
