In his latest book, Wounded Tigris, due to be published by Corsair on April 6, Leon McCarron aims to show what humanity stands to lose if the great river — threatened by both climate change and geopolitics — is allowed to die. There’s an interview with the author in the April issue of National Geographic Traveller UK, which you can already read online. In it, he explains why his current base is Iraqi Kurdistan, where, with a Syrian Kurdish filmmaker, Lawin Mohammed, he has been working on a hiking trail through the Zagros Mountains.
