This is one of the best free paranormal romances I've read in a while - I'd probably be safe in saying that it's the best one I've read all year.
I know that's not saying much. The bar is set pretty low, after all.
I genuinely liked this story, though. The idea of fallen angels needing to coexist with demons, because poachers kill them for their feathers was a fascinating premise.
Kestrel and Saffron were great together, too. There was a Romeo and Juliet thing going on, where Saffron's father was one of the most notorious collectors of angel feathers, and a lot of the romantic tension in the story came from the two of them trying to overcome their prejudices and understand the other side's story. They judged each other for who they were, not for who their families were.
The writing was clean, and well edited. The world was interesting. The main characters were engaging.
The only real complaint I've got (and it's not so much a complaint as me picking at a plot hole) is the fact that nobody knew that Kestrel was the one who tipped off the Morins.
There is an angel who can read minds, who has been proven to not need permission to enter somebody's mind, who goes on daily flies around the city with Kestrel. An angel who would be absolutely pissed if he knew that Kestrel was the one who spared the Morins. An angel who knows that Kestrel is in love with Saffron, and was hurt by his betrayal of her trust. And yet, Kestrel tells Saffron that nobody knows he was the one who tipped her family off.
Despite the fact that while Saffron's gone, she's all he can think about, and he's got to be thinking about the fact that she left, even after he saved her parents.
And nobody knows that he did it?
I don't buy that for a second.
Like I said, though, I really did enjoy this book. It's books like this that keep me going through the free stuff I find on Amazon.
