Perhaps you are right, clintACK. Incidentally, I loved that quote of Mab and I really wanted to know who were those "very confident" beings. I think she may have been talking about some of her own people too, as well as Summer. But who else? The ghouls?
To be honest, they have every reason to be afraid. Harry not only is a starborn, the Winter Knight, the Warden, and a powerful wizard on his own right, he also has friends. From werewolves to River Shoulders, from KotC to the wee folk. And they don't even know that Lara needs him alive.
