*Spoiler alert!*
This book is officially my all time favourite. Regan is a really original character and you keep having great mysteries. Thankfully there is no love in the story, because, to be honest, all the cliché love stories are getting a bit boring. The writer worked out the characters really well and there also aren't any mistakes. There keep being cliff hangers, which has you sitting on the edge of your chair, waiting for the next chapter. In my opinion it isn't really sure what Regan's craft is, because she is also really good at pushing her body past the normal limits, even with a fatal wound to her chest is she capable at beating someone, whom she hasn't beaten before. Also is 'the burning sun inside of her chest', her rage extremely big. So, who knows, maybe there is more to her then what reaches the eye.
Another aspect that makes this story so interesting is Regan's struggle with herself. Everyone around her says she is softening, bus she denies it, because she can't use a conscience for her revenge on Kessler. And everyone seems to hate her, but somehow they all help her?!
A point that can get slightly annoying, but at the same time is really good, are the conversations between Kessler and Regan. They are mostly about the same thing, but they are also really good because I wouldn't be able to think of so much rude things to say to one person. But the possibility that I don't like the conversations because they are insulting for Regan, is fairly big...
Anyway, my conclusion is that Darkness Girl is really good and that we should start some kind of fandom!
