"I’d come to the conclusion that no one had done it. No one had survived out at sea at night-time floating in the water" - Rob Hewitt Rob survived three nights adrift at sea after becoming separated from his dive boat. Fiona was travelling down the Amazon River in Ecuador when she was kidnapped. James was on the 92nd floor of the World Trade Center's South Tower on September 11.

She asks what drives people to fight for life – and whether the battle to survive is worth it.
