First off, the cover was devastatingly beautiful. I've always been a sucker for beautiful covers, so that definitely drew me in.
But come for the cover, stay for the plot. I've never read something so heart breaking and enchanting. It's a bone deep ache that really gets to you. Your heart clenches and just cannot unclench.
I really liked Cohen and the line that was getting blurred between real and imaginary. It's a concept that's so brilliant (maybe a tad bit overused, but I like it just the same).
You know already that Cohen is a flawed character because you learn from the synopsis itself that Cohen questions whether he is responsible for his father's death. But the beauty is all that leads up to there. The tragedy is so complex but not too complex. Altogether, a great read.
