During 2010 Mark Thomas decided to go rambling in the Middle East and walked the entire length of the Israeli Separation Barrier, crossing between the Israeli and the Palestinian sides. This is the story of 300,000 settlers, a 750 km wall, six arrests, one stoning, too much hummus and one simple question... 'Good fences make good neighbours, but what about bad ones?'.

The Israeli security wall is going to be over 1,000 km long when completed and will surround most of the West Bank. Seen by some as a cynical land grab and others as an apartheid barrier, opinions on it are hugely divided. It has been declared illegal under international law and its impact on life in the West Bank has been enormous.

But who are the people who live in the shadow of this wall and how does it affect their lives? Mark decided the only way to really get to grips with this huge divide was to combine his two great loves, walking and talking, and using the barrier as a route map, he 'walked the wall' - covering the entire distance with little more in his armoury than mint cakes and a box of bandaids.

Rambling in both senses of the word is a great British tradition and Mark throws himself into both on his extreme journey, accompanied by Israelis and Palestinians - ordinary folk who help him on his way, chat and tell their stories... and who will hopefully put him up.

With diversions off-route to see Jewish settlers in dub reggae bands and Palestinian brewers who make Arab beer, the course of his ramble sees him tear-gassed, stoned, sunburned, rained and hailed on, and even losing the wall a couple of times. But thankfully he was also welcomed and looked after by those farmers, soldiers, smugglers and zookeepers he met, and finally he earned a unique insight into the real Middle East in all its entrenched and yet life-affirming glory. And all without hardly ever getting arrested - much!
