Bod and the graveyard

This book has gotten more interesting, and even more crazy when I thought it couldn't, I mean the kid is being raised by ghosts. Like when he is still human but can still talk and interact with ghosts and humans at the same time and can can travel into tombs, graves, and stuff like that. But this is a fiction book so what do you expect; even though unbelievable, just use your imagination and the book makes more sense. Are you enjoying the book or is it to unrealistic?
