Julie Nicholson
52 people died and nearly 700 were injured when suicide bombers caused a series of explosions in London's transport system on July 7th 2005.
Among the dead was 24 year old Jenny Nicholson.

Jenny's mother Julie was an Anglican Priest, based in Bristol in the West of England.
After Jenny's death, Julie gave up her job. She said she found she could no longer preach forgiveness from the pulpit whilst being unable to forgive the bombers who killed her daughter.
Five years on, Julie has written a book called 'A Song for Jenny' in which she describes what she calls the "strange country of grief" and her own personal struggle with her faith.
Matthew Bannister spoke to Julie about the day of the bombings and how she and her family desperately tried to contact Jenny.
A Song For Jenny by Julie Nicholson is published by HarperCollins.
