I loved Regin and Declan's story. It was a fantastic tale of undying love and what I liked most is that even though Regin was fully willing to accept her man without question there were obstacles between them. 
 I loved hearing about the other reincarnations of Aiden the Fierce (Declan) and how they'd been with Regin only for Regin to realize that the difference with Declan is that she actually loved him in all his scared and tormented glory. 
 Declan's previous torture at the hands of evil Lore creatures really made for an interesting tale because right off the bat he hates all Loreans which would include Regin. The thing is that Declan is hiding his own abilities though he has yet to realize just what he is. 
 The hard part for me was that with everything Declan ends up doing to people of the Lore, it seems like life with Regin would be an impossible goal but Cole seems to make it easy. Normally, I'm right with her as she always does a fantastic job but in this I'm skeptical. Regin may have been willing to forgive and forget but so many other Loreans wouldn't be able to simply sweep it under the rug even with the protection of Nix. Still one of the best of the series. 
 Also the glimpse into Lothaire was interesting as was the strange relationship he seems to have with Nix but I have yet to become really intrigued by his character. 
 I can't wait for Lanthe, Uilliem and Carrow's tale (I read this book out of order).
