Cosmo is a young boy whose life has been changed forever, after falling out of the tree he loved to climb. Now, Cosmo is disabled and uses a wheelchair. Now, Cosmo wants to have a conversation with the tree.

In this outstanding debut collection for children, Stephen Lightbown draws on his own personal experiences as a wheelchair user, while creating a unique and utterly engaging character in Cosmo. Written in Cosmo's voice and peppered with contributions from the boy's family, these poems take the reader on a journey of challenges, questions, hurts, explorations and triumphs. Cosmo is endlessly open and curious, and his observations and reflections are at once perceptive, raw, hilarious, confronting and enchanting.

How can Cosmo come to terms with, and adapt to, this seismic change in his life? Is his life as he knew it gone? Could there be new possibilities ahead, and also new abilities that Cosmo doesn't yet know he possesses? And will the tree ever reply to his number one question: why?
