I have to wonder if the wizarding world isn't glad that someone with Harry's power and reputation has "disappeared"; there's less chance then of him becoming a rallying point for those who oppose the latest iteration of the established order. I am surprised that Hermione's not looking for him (or is Ron keeping her too "busy"?) and I have to wonder if this is using a touch of canon with Dobby's death.
Meanwhile, this is a distinctly different twist on the "Harry leaves the wizarding world and establishes a new life" genre. I'll be looking forward to further installments including his meeting with Dr. Thomas Wayne and his family.
