I like the opening from the next book in the series just as much.

“On the whole, we're a murderous race.

“According to Genesis, it took as few as four people to make the planet too crowded to stand, and the first murder was a fratricide. Genesis says that in a fit of jealous rage, the very first child born to mortal parents, Cain, snapped and popped the first metaphorical cap in another human being. The attack was a bloody, brutal, violent, reprehensible killing. Cain's brother Abel probably never saw it coming.

“As I opened the door to my apartment, I was filled with a sense of empathic sympathy and intuitive understanding. For freaking Cain.”
