This was a slog of a book from the beginning, and I marked it DNF. There's no charm to this story, and all of the characters felt flat. Katrina's a mustache twirling villain, and it's not that there's a lot introduce early in the book, but the world building is so thin and clumsy that I never got interested in the story. Katrina is a fire elemental, but this book starts too fast for me to care about Cade or Katrina and their backgrounds. Then it switches to Mara and her sickness too fast for me to care about her. Then 'weeks, even months' pass, which is a huge time skip in the first quarter of a book. A time skip this large at the beginning of the novel means that it didn't start in the right place. I really love werewolf books, but I have to care about the characters for them to work, and that never happened once in the first third of this book. The characters were just thin to me, and I never connected with them.
