I thought this book was good enough to finish, but I won't be buying the sequels. 
 I'm a big fan of books with multiple narrators because I like to see inside of the different characters' minds, but The Red Knight just has way too many. By the time I'd been through one "rotation" of characters, I couldn't remember who each person was and I had to go back and re-read their chapters from before. I found myself constantly wondering why each character was included. It was tied together some at the end, but the ending (which I won't give away) was the only part that made me interested in the sequel. The rest of the book was mediocre at best. 
 The best part of the book was the main protagonist- the "Captain." I loved that character and the other characters were well-developed too. 
 As far as the plot goes, I thought it was full of promising ideas that weren't executed very well. 
 Then I read Game of Thrones and I realized that it had the same promising ideas, but it was executed better. So basically, The Red Knight is a poorly done Game of Thrones knock off. If you like the ideas in The Red Knight but you don't want to waste your time, I suggest reading Game of Thrones.
