There were a few things that slightly jarred on me with this book, one of which was the rapidity with which Tiago 'fell in lust' with Tricks/Niniane. If you have read the first in the series (Dragon Bound), then the exchange between them in that book kind of sets up the attraction, but if you haven't, then it seems a tad sudden. Having said this, the rest of the book was excellent, again with a central mystery/action plot that keeps you wondering - in this case, it's who is behind the attempts on Niniane's life. It is signposted slightly obviously so you do expect it when the final attempt pops up, but it isn't massively clumsy.
Basically Niniane was revealed as the heir to the Dark Fae throne in the last book (once Urien was killed) and she now has to take up her position. At the end of book 1 it had been decided that, for political reasons, none of the Wer could go as protectors or bodyguards, so she has to do it all alone. There is an attempt on her life, which is video-d and put on youtube, and Tiago leaves to find her and 'take charge'. There is a second attempt on both their lives, confusion in the Dark Fae court, the involvement of the vampire Carling (who stars in book 3) etc etc. Meanwhile Tiago decides that Niniane is his mate, she realises that she loves him but her court will never accept him (or their children). A truly spectacular near sacrifice at the end brings everything into perspective and all ends well. All good fun that keeps the pages turning.
Still interested, and now moving on to book 3
