"A Monster Calls" by Siobhan Dowd and Patrick Ness

Side note: This book was started by Siobhan Dowd and finished by Patrick Ness because, sadly, Dowd died before she could finish it, which is a real shame. If you haven't read any of Dowds earlier books then your doing yourself an injustice. I strongly recommend them to all those who enjoy a good mystery and also a gripping fantasy; one of my personal favourites is "The London Eye Mystery". Drop a comment if you would like to see a review on it later on.

The opening scene is in a house; the bedroom of a teenage boy, Conor O'Malley when he's experiencing a horrific reoccurring nightmare... Or so he thought.
He envisions the giant, towering yew tree in the back field, alive. As it moves; shuffling towards the bare brick outer shell of the house, and Conor's window, it speaks his name in a deep, resonating voice; I've come to get you Conor O'Malley...
The monster proceeds in telling 3 stories in return for a 4th; the truth about Conor's reoccurring nightmare. The stories uncover the truth about the monster and Conor in ways he could never have imagined and cure Conor of the thing he has been plagued by, that horrible thing that had been visiting his dreams ever since his mother fell ill...

RATING: 10/10- A superbly crafted book with plenty of twists and turns along the way; all the way up to a really emotional end. A brilliant read! One of my favourite books.
