The other reviewer is right to call this account a slog, but that is precisely what Greene's journey was. He decided to journey through a land where a white man is seen perhaps twice a decade, to people who live a simple life.
If you're looking for a thrilling, edge-of-your-seat novel of semi-truths this is not the book for you. If you have an interest in West Africa, Liberia, native living, superstition, colonialism, exploration, and generally Greene as a person this book is good. I found digesting in two chunks a more managable read.
Certainly very different to Greene's other writings, but for me gave an interesting perspective on an unusual country and a remarkable man.
