Kate Frost was born in Bristol in 1977. She grew up in a Victorian terraced house in Horfield with her Mum and Dad and younger brother, Thomas. At seven-years-old two major things happened: the first was open heart surgery at the BRI to fix a hole in her heart; the second was the home tutor Kate had following the operation, taught her how to write stories. Kate's first novel was a time travel adventure set during the Great Fire of London called London's Burning.

In 1995 Kate moved to Aberystwyth to study BA Hons Drama, where she spent three very happy, drunken, yet productive years within the Department of Theatre, Film and Televison Studies. Kate played King Charles II in an all female production of Stephen Jeffrey's The Libertine; Frida Kahlo in Greg Cullen's Frida and Diego and Angustias in Federico Garcia Lorca's The House of Bernarda Alba.

After graduating, Kate spent a year going to auditions but became disillusioned with acting and so started writing again. In December 1999, a year and a half after leaving Aberystwyth, Kate had her first article, See You Next Year published in small press magazine, Acorn. More followed, with short stories being published in QWF, Scriptor-4, The London Magazine and Peninsular. New Welsh Review and Chapter & Verse commissioned Kate to write various articles on subjects such as the National Youth Theatre of Wales and William Makepeace Thackeray. In 2003, Kate took part in bestselling author, Kate Mosse's Labyrinth Baton Stories Competition and was one of the winners. An early draft of The Butterfly Storm was longlisted for the Yeovil Prize 2005.

During this time Kate had various jobs; she unintentionally worked her way in to the management team at Warner Village Cinema but quit after three years to concentrate on her writing. She did odd jobs after that, working as a Virgin Vie Consultant, as a sales assistant at Waterstones and now works for NHS Direct as a Health Advisor. Kate also works as a Supporting Artist for Mad Dog Casting and has appeared in Vanity Fair, King Arthur and The Young Visiters and Casualty for the BBC .

Last year Kate graduated from Bath Spa University with a MA in Creative Writing. The Butterfly Storm is the result of that year.
