This was so good!! Such a fun story, very easy to read and follow the characters’ journey. The characters were all so well written, Kas and her past and her becoming a slayer and just how kind she was, Claudia and her story with being half a vampire but also how she set the whole plot in wanting to stop her Serisa from destroying the whole world, and Serisa, who even though she was the villain and wanted to end mankind, she had suffered so much and just wanted to ease her pain and get revenge. The romance was perfect, it took a while for them to notice each other but the yearning was done so well and I was giggling and kicking my feet every time they as much as glanced at each other. This book could’ve benefited being a bit longer and some scenes a bit more developed, and some parts felt like they happened too easily to keep the story moving, while it had made sense for there to have been a bit more struggle or suspicion from the characters. Nonetheless, very much enjoyed reading this.
