British physician and author Rachel Clarke tells the story of Keira Ball and Max Johnson – two children who changed the law on organ donation in the UK.

Losing a loved one is one of the hardest experiences anyone can go through.

While we all have our own ways of coping with death, knowing that the ones we've lost can help to save other people through organ transplant can bring meaning and comfort.

Rachel Clarke is a British journalist, author, and physician who specializes in palliative and end-of-life care.

In The Story of a Heart, Clarke explores how a heart transplant saved a nine-year-old boy in the UK and changed British legislation to make organ donation available to more people in need.
