As the Author, he has power in as much as he can wield the quill and potentially rewrite or control history (much as Isaac did). Henry slips occasionally, but for the most part he has made a concious effort to limit his abuse of the power of the quill. Still, his writing the stories of the Underworld denizens to show them their unfinished business was a very beneficial use of his author power, and something that none of the others could accomplish. So, in this sense, Henry definitly has power of his own, and it is not insubstantial. (imo)

Also, there is the question of his Heart of the Truest Believer. That could just be a description of him, but scenes like the (campy, cheesy, and over the top) speech in front of the NYC library make me wonder how much of what happened was a result of people just going with the moment and how much of that might have been a result of Henry's power of belief extending out and affecting his surroundings. That might be an interesting concept to explore in future storylines (as maybe a b or c plot, not the main storyline).
