I greatly enjoyed this. Professor McWhorter was lively in his delivery, throwing in odd quirky comments, such as likening languages to his cat, but keeping the pace of information going well.
I had thought I might want to alternate with listening to fiction, but this kept me engrossed while cycling and interested enough to swop over to listening to this rather than the radio while driving.
For those wanting to judge the level you could probably put it as being similar to the In Our Time programmes, although of course those are debate, whereas this is a series of many short lectures.
This is a very detailed and well written book about the world history. The book starts with the first evidence of mankind on Earth and takes it to the present. It is a fun to listen to the interesting anectodes and lesser-researched areas of the history. Each chapter focuses on a different aspect and the approach is clear and well documented. Recent research findings are also mentioned which makes the listening experience even more interesting. The narration is very clear and a pleasure to listen to.
