Patrick Ness is one of my favourite authors hands down! His narrative is always beautiful. Although his stories might be a little weird at the begining, it doesn't matter what it is about at the end of the day you're going to relate to it. A monster calls is no exception, so beautifully written and with such a real, though but positive message. 
 What made me fall in love even more with the book was the author's note. Usually I don't read author's or editor's notes because I want to get to the story already, but I'm so glad I casually did read it after I finished the book. For those who might not know, this was supposed to be Siobhan Dowd's fifth book, but she passed away of breast cancer before she could write it. The idea was passed to Ness, who developed Dowd's story with his own voice. That felt very special to me. Although I have never read any of Dowd's book, I'm definitely going to pick one up after this. 
 I would recommend this book 100%
