What is the external conflict for breathe a ghost story?

To tell the truth there really and truly isn't nothing wrong with Breath the Ghost story. This story is probabley a must to read. The only problem i see in this book is the conflict and comotion that lies in the book in beween pages. As the Ghost Mother makes a new "son" i suppose you could call it. Jack (the main character) finds out that "Ghost Mother" isn't what he figured she is. From here on out if this interests you then I'm goning to have to suggest you read this amazing book!!!!!
