I'm really vacillating between a 3.5 and 4. On the one hand, this is everything I love about vampires and their relationship(s) with humans and the depths of morality vs. immorality with the backdrop of mortality and immortality. I love how absolutely unhinged Kidan and Susenyos both are; they truly are a toxic match in the making. On the other hand, there were a few times I found myself lost in the overall arc of the story and knowing exactly when Kidan's motives changed. Knowing this is a trilogy, I'm excited to dive into the second book to get some answers. I think Immortal Dark left off on a <i>really</i> good place to pick back up on. I'm not 100% sold with the supporting characters that are Kidan's friends except for GK, who had a pretty distinct personality from Slen and Yusuf. Slen felt too much like Kidan, and Yusuf felt too much like GK until he didn't... if that makes sense. Death's presence truly lingers over Kidan, which was a plus. Ah! I'm excited for the next! Bring on more sexy college vampires!
