FALLEN is the latest book by Callie Hart and delves deeper into Sloane and Zeth’s complicated relationship. Readers should start with DEVIANT to get the full impact of their anger and angst towards each other. Over the past few books, they have been dancing around their feelings but in FALLEN, I could see that their feelings are starting to surface more. Zeth realizes that Sloane doesn’t need him anymore because she’s found her sister, for better or worse. She could leave him at any time. He’s afraid to admit that he likes that she challenges him at every corner and complements his dark side without being scared off. At first she was freaked out by Zeth’s outspoken attitude but I think she gradually enjoys being with him. He brings out her sexually and accepts her in every way which both frightens and endears her to him. Their games are not for the faint at heart and should come with a warning label. Combustible and flammables inside!! The secondary characters are very important to the story and I hope as their story continues to progress, they get these characters get their own stories because some of them definitely have something to say… For me, FALLEN opens up a new door for Sloane and Zeth’s relationship. The cliffhanger had me hearing the songs 99 Problems and Bonnie and Clyde racing through my head….
