“Man, Bob. I know you can be an annoying git when you want to be one—but what did you do to make Mab mad at you?” “It isn’t what I do, Harry,” Bob said in a very small voice. “It’s what I know.” I lifted an eyebrow. It took a lot to make the skull flinch. “And what is that, exactly?” The lights in the eye sockets dwindled to tiny pinpoints, and his voice came out in a whisper. “I know how to kill an immortal.” “Like Maeve?” I asked him. “Maeve,” Bob said. “Mab. Mother Winter. Any of them.” Holy crap. Now, that was a piece of information worth killing for.
