Amanda Walker felt trapped in a flat she couldn't sell because of its flammable cladding.
When it turned out that no government scheme would cover the costs of removing the dangerous material from her newly built flat in south London, she started campaigning.
She spent four years trying to get justice for herself, and for millions caught up in the scandal exposed by the Grenfell Tower fire.
Then, at the age of 51, she was found dead in her one-bedroom apartment by her mother and sister. An inquest recently recorded a verdict of death by misadventure.
"She would often phone me late at night when she just couldn't deal with it any more," her mother Glenda recalls.
"I wish she could phone me now."
