While studying for a degree in Psychology, Kate Medina joined the Territorial Army where she spent five years, first as an officer trainee and then as a Troop Commander in the Royal Engineers.

After leaving the TA she worked in publishing as Managing Editor, Land Based Weapon Systems, at Jane's Information Group, where she was responsible for providing information on small arms, armour, artillery and land mines to global militaries. Whilst at Jane's she spent time in the Middle-East and in Cambodia, working with mine clearance charities in Battambang to provide them with information that would help mine clearers deal with complex mines and IEDs more safely in the field.

She has also worked as a strategy consultant with McKinsey and Company, and has lectured in business and consulting at London Business School and the London School of Economics. She recently obtained an MA in Creative Writing from Bath Spa University and now writes full time. She is dual British/Australian nationality, loves other countries and cultures and has travelled extensively throughout the developing and developed worlds.

White Crocodile, her debut thriller was sold to publishers around the world in 2014/15.  Set in the land mine fields of Cambodia and featuring a strong female lead, White Crocodile was called a 'remarkable debut' in The Independent, 'a stunning debut' in the Sunday Mirror and 'evocative' in The Times.  She was also invited to talk about White Crocodile and the devastating impact of land mines in developing countries on Radio 4, Women's Hour.

Fire Damage, her new novel, is the first in a series featuring clinical psychologist, Dr Jessie Flynn.  It has received excellent reviews in all the major UK national newspapers, including the The Times, The Independent, The Daily Mail, The Sun, The Mirror, The Sunday Express and the Herald Scotland.

She lives in London with her husband and three children.
