It's rare that I read a book and don't really know what to think about it, but that's the case with The Falcon Throne. I've enjoyed other books by Karen Miller, and I certainly didn't dislike this book. It just seems like this book was written to cash in on the popularity of Game of Thrones.
Both works have Throne in the title. Both books are fantasies set in pseudo-medieval kingdoms. Both works are about politics with lots of treachery and backstabbing and power-hungry lunatics who want to seize a throne at all costs. Both works have large numbers of major characters. Both works keep magic more or less in the background. Both works tell fairly dark stories.
I'm not saying that Falcon is a copy of Game, because it clearly isn't. It is, however, very much the same sort of story. If you enjoy Game of Thrones, the books or the TV show, you'll probably enjoy this. Unfortunately, its also long, fairly depressing, and you will see bad things happen to characters you like.
Personally, I will probably pick up the rest of the series when it's written.
