In this initiatory journey, Lawrence brushed death, discovered the wonderful and astonishing region, and encountered someone who changed his life. Almost a century later, the well-known writer Sylvain Tesson travels on Lawrence’s steps, with the intention of tracing back the history of this mysterious adventure who started the legend of Lawrence d’Arabie.
