Laurent Petitmangin was born in 1965 in Lorraine in a family of railway workers. He spent his first twenty years in Metz and then left his home town to pursue higher education in Lyon. He returned to Air France, a company for which he still works today. A great reader, he has been writing for about ten years. Ce qu’il faut de nuit, his first novel published in the autumn of 2020, was a huge critical and public success in France and abroad, immediately establishing the author as one of the voices to follow on the French literary scene.
