On today's episode of Brainwaves, we talk to Ela Simon, co-author of The Bipolar Express. Written with her daughter Natasha, the book describes the “rollercoaster of mania and depression” as experienced by mother and daughter. We talk about what it's like to care for a child with a mental illness, and also about her experience of writing a novel with her daughter and how the journey brought them together.You can find out more about Ela and Natasha at their Facebook page and their website.
