I think I did not realize that this is a thriller. Granted I haven't read many thrillers, but this feels more like sci-fi thriller than fantasy to me. But also, I didn't feel like it was that thrilling of a thriller. There wasn't a big mystery really. There were some bigger revelations, but most of that happened early on it felt like. This was very character focused so if you like Victor and Eli I think you'll Vicious. For me, I just didn't find any of the characters super fascinating. And the focus wasn't really on the superpowers or "magic" all that much. None of these are really negatives, just good things to know. I enjoyed Vicious and I read it quickly. I think the book did what it set out to do: present a corollary to the traditional good superheroes with complex antagonists. I just didn't care enough about the characters to love Vicious and there wasn't enough else for me to love it despite the characters.
