I absolutely loved this book. I read the others in this series a couple of months ago, so I did not have to wait long for its release, thankfully. Callum's story goes deeper than the other two books, and the development of his and Everly's relationship is unique. And yes, the appearances of Zane and Leon and this perspective of the story are smoothly all tied in together. The author is descriptive when it comes to people, places, and emotions. I think I am going to have to go back and read them back-to-back with everyone's perspective now clear. I would highly recommend this series and, as usual, say please read trigger warnings.
