Started this on the recommendation of Jacopo. He told me the plot of the prequel, The Dark Glory War. It's a really interesting story, but, of course, some elements that it could do without. The last book in the series is coming out soon - or maybe it already has? - so I'll have to read the others soon.
Fortress Draconis is about a young thief named Will who learns that there is a prophecy concerning him, saying that he'll be the one able to defeat the tyrant princess/sorceress, Chytrine. Will is a fairly believable character, even though overall the story follows some very generic plot devices. Regardless, I enjoyed it, and I'll read the subsequent books.
