Three and a half stars. I found it even better than its predecessor, The Iron Hunt, however, it still suffers from some of the same narrative confusion. One of the less coherent parts of Lui's narrative is when she has Kiss, the lead character, unintentionally jumping through time and space. I think most of the confusion stems from Liu intentionally creating mysteries, in this case related to unknown abilities of a silver ring/sword she picked up in The Iron Hunt, but as a reader, it gets confusing as to where these abilities come from, why Kiss isn't more disturbed, are they under control, etc. There's a new challenge related to Grant's abilities, and why using them now is starting to cause extremely negative health effects. There's the mystery of Byron. And although the book is called Darkness Falls, there's only a little bit of mystery related to the "darkness" inside of Kiss. It is a very action-oriented book, so there aren't many points where Kiss has an internal narrative that clues in the reader as to how she thinks about these things and what the implications may be. I do like the Kiss character, her strong sense of identity, her mission, and her awareness that falling in love with Grant changed a lot of the expectations she had for her life. Her relationship with "the boys" is unique and fun, and the characters around her are interesting, although all of them seem to have their own little "mysteries" surrounding them. Maybe that's a narrative device to keep us reading, wanting to learn more and to put the pieces of the puzzle together, but Lui's story could use a little more filling in, so that readers weren't so lost.
