The bestselling novel about love, loss, and hope by two-time Carnegie Medal winner Patrick Ness. Conor has been having the same dream every night since his mother first fell ill, since she started treatments that don’t seem to be working. But tonight, everything is different. Tonight, when he wakes up, a visitor stands at his window. He is ancient, elemental, a force of nature. And he wants the most dangerous thing of all from Conor. He wants the truth. Patrick Ness takes the last idea from the late, award-winning author Siobhan Dowd and weaves an extraordinary and heartbreaking story about mischief, healing, and above all, the courage it takes to survive.
