The 10th anniversary edition of the bestselling novel about love; loss and hope from the twice Carnegie Medal-winning Patrick Ness. Conor has the same dream every night; ever since his mother first fell ill; ever since she started the treatments that don't quite seem to be working. But tonight is different. Tonight; when he wakes; there's a visitor at his window. It's ancient; elemental; a force of nature. And it wants the most dangerous thing of all from Conor. It wants the truth. Patrick Ness takes the final idea of the late; award-winning writer Siobhan Dowd and weaves an extraordinary and heartbreaking tale of mischief; healing and above all; the courage it takes to survive. Since publication; A Monster Calls has become an international bestseller and been made into a film starring Felicity Jones; Liam Neeson and Sigourney Weaver.
