Let me start out by saying: I /love/ Dragon Age. I'm pretty close to the end of Inquisition and I just wanted to live in the world of Thedas a little longer. I read "Last Flight" last semester and loved it, so I figured I'd start at the beginning and picked this one up. 
 I liked this book, to a point. It was written well enough, pretty good pacing, and characters were well drawn - up until the last 75 pages or so. It ends much too abruptly, in a really weird spot, and I found myself really wanting by the end of the book. There is a complete 180 in Maric's character that leaves a lot to be desired about how he eventually ended up winning the war, how he dealt with it, how his relationships changed, etc., that never ends up getting explained. In short, I felt I only read 3/4 of a book. It needed another 200 pages or so to tie everything together and leave me satisfied. "Last Flight" was much better than this one. I'll read the rest eventually, while I'm not taking YA lit XD 
 If you like Dragon Age, or if you just plain like fantasy, you'll like this book. It might clear up some lore for you like it did for me. You'll have fun reading it, up until the very end, where you'll have a lot more questions than answers. If you're new to DA pick up the games first so you're not put off by the book!
