Viv Sang was born in Northwich, Cheshire in the United Kingdom. She was educated at Northwich Girls' Grammar School and at Elizabeth Gaskell Teacher Training College in Manchester. She taught Science, Maths and English in Salford and Heywood, Lancashire until she had her first child. She then stayed at home to bring up her two children, a girl and a boy, until her son started school when she returned to teaching. She was now living near Southampton, but the family moved to Redhill in Surrey and she then taught in Croydon. She took early retirement in 2001 and moved with her husband to East Sussex.
As well as writing, Viv enjoys many crafts and also paints.
