I love this book. It’s rambunctious. It rolls round the tongue. It’s a time machine to take you to the late Georgian era on an adventure with Mungo Park on his two trips to find the source of the Niger. It’s not sanitised history – London is filthy, life is harsh and medical procedures make you wince. When I first read it, I couldn’t put it down. I still pick it up, years later. The prose is so good it’s like poetry. When TC Boyle, the author, came to the Edinburgh International Book Festival I sat in the front row listening to him like he was a god!
