When twenty-year-old Katherine Jenkins was performing in a Christmas concert with her college choir at the Brangwyn Hall in Swansea, there was an enormous bang as she hit the high note in 'O Holy Night'. Worried they were being shot at and fearing for their lives, the audience immediately ducked for cover. But they had nothing to fear. It was merely Katherine's powerful voice that had shattered one of the chandeliers above the stage. Katherine Jenkins' story began, quite unusually for a classical singer, when she was offered a recording contract immediately after leaving college - a six-album deal with Universal Classics. Her debut album Premiere went straight to number one in the classical charts in April 2004 and stayed there for eight weeks, outselling operatic greats like Kiri te Kanawa, Lesley Garrett and Angela Gheorghiu. For Jenkins it was a dream come true. Now, in her candid autobiography, she reveals how her passion to make this dream reality transformed her from a trainee teacher to one of the most famous classical singers in the world. This is the story behind that beautiful and angelic voice.
