In Grave Peril, Harry crosses into the Nevernever from his apartment living room. It goes to "his apartment, only a bit cleaner and brighter". In Changes, he crosses from his lab (only one room away), and ends up in a garden with a primrose path (I see what you did there ). So, do different parts of Harry's home lead to different parts of the NN, or did the NN 'next to' his apartment change between the two books?

(In the search results, this was only discussed kind of tangentially)
