One of the reasons no one answers you is that I don't think anyone really reads Knighthood. Because it's not very good, but it's also not bad in an interesting way. It's just there. It's derivative and bland and not even worth reading to see "Oh what is it this time?" if you were the sort so inclined.
The problem with Knighthood is that it gets one of the premises of single protagonist-centric fiction wrong. Such a series is supposed to hook you by making you think that the main character is interesting in some way, and draw you in by showing you why they're interesting, how other people relate to them and are connected to them, and that way get you interested in the challenges they face.
The problem with Knighthood is that it's clear that the writer just takes it for granted that everyone finds his main character as interesting as he does. He thinks she's fascinating and amazing and cool, and so just proceeds under the assumption that it goes without saying and all he needs to do is keep giving her opportunities to show it off. Which is great if all you're looking for is someone to do some super kung-fu and that's all it takes to get you invested in a character, otherwise it's just kind of meh.
In other words, Knighthood's failure started from the beginning with how it tells its story. You can't "fix" it at this point without starting over.
