This is the second in a series by Shana Abé about the clan that live in remote northern England - the clan has a secret, that they possess the ability to Turn into smoke or dragons. Unfortunately not all of the clan can Turn, Lady Amalia Langford, daughter of the hero and heroine of the first book in this series (The Smoke Thief), isn't able to. However Amalia, or Lia, is keeping some secrets - although she can't Turn she seems to be having dreams about the future and they involve Zane, a human and a master thief.
Zane and Lia find themselves travelling to the Carpathian mountains in search of a special diamond, known as Draumr, which has the power to enslave her kind, the Drákon. They soon find themselves in company with others of Amalia's kind - who may not be peaceful toward them. Zane's position as one of the few humans to know about the Drákon tribe means that his life may well be forfeit and Lia's window into the future shows her that things will not be good. For Zane, finding the diamond will bring him riches, but Lia knows that if Zane has it her future will not be good.
This book is a very easy read, even if the first book in the series hasn't been read. Amalia and Zane are both great characters with Zane particularly an amalgamation of the events of his difficult childhood and his own mental strength and resourcefulness. The romance side of this book takes a back seat against the actions, including travelling by coach into central Europe, meeting other dragons and finding the diamond, and in some ways the romance isn't very well fleshed out, but it's an enjoyable read and an interesting twist on the dragon legends.
