When James Cook's daughter was nearly one, he began to suspect that she wasn't simply a 'late bloomer', as he and his wife were telling friends and family. Emily was strongly taken by images and patterns around the house, had a marked response to music, but never pointed at anything, and hadn't crawled yet.

At the age of two-and-a-half, after months of invasive tests, Emily was finally diagnosed with severe autism, and everything changed.

Forced to embark on a fraught journey from denial to acceptance, James discovered the multi-faceted link between music and autism, and how singing and playing guitar for Emily could provide a unique form of communication.

In Her Room is an extraordinary and heartbreaking story of a father's attempts to connect with his daughter, and how music can help bridge the divide.
