What if everything we think we know about addiction is wrong? Johann Hari's TED talk on this subject - and the animation based on it - have been viewed more than 20 million times, and this New York Times best-selling book takes you on the remarkable journey that led him to uncovering these breakthroughs.

One of Hari's earliest memories is of trying to wake up one of his relatives and not being able to. He didn't understand why then, but as he got older, he realised he had addiction in his family. He wanted to understand what really causes addiction - and how to find our way back from it. So he set off on an epic three-year, thirty-thousand mile journey into the war on drugs and addiction. He discovered that nothing on this subject is what we have been told it is - and the solutions are there, waiting for us, if only we are ready to see them.
