Born and raised in Houston, Texas, Kelleigh lives between Los Angeles and London.  She earned a BFA (Directing) from Carnegie Mellon University, studied screenwriting at the University of Southern California, and has been honoured by the Academy of Motion Picture Arts and Sciences as a Finalist for the Nicholl Fellowships in Screenwriting, among numerous screenwriting accolades.  She was awarded the Abroad Fellowship in Provence in 2006, where the germ of an idea for a novel about Truman Capote’s betrayal of his inner circle was born.  After a decade of research, Kelleigh began Swan Song, her debut novel, in the UEA/ Guardian Masterclass, completing it four years later on the UEA Prose Fiction MA, from which she graduated with Distinction.

Prepublication, Swan Song was the winner of the Bridport Prize Peggy Chapman Andrews Award for a first novel, was longlisted for the Bath Novel Award and shortlisted for the Historical Novel Society New Novel Award, the Myriad Editions First Drafts Competition and the Lucy Cavendish Fiction Prize.

Swan Song was published in 2018 by Penguin Random House/ Hutchinson.  It was the winner of the Society of Authors’ McKitterick Prize, was named one of the Books of the Year by The Times, and was longlisted for the 2019 Women’s Prize for Fiction.

Kelleigh is currently adapting Swan Song as a limited series for television and working on her second novel.
