So, having finished The Silk Roads (which I whole-heartedly recommend), I've dived back into Revolutions which is presently all about the Mexican Revolution. I've certainly learnt a lot, and it's been made more interesting as places that I travelled to during my one (work) visit to the country have been mentioned. I think there are a couple more episodes, then a short break, and then we start the Russian revolution. I may well listen to Jared Diamond's Guns, Germs and Steel before that to build up a backlog to binge through.
I also listened to Limetown Series 2 which was a little disappointing, and I found the ending a bit of a letdown. I was going to pick up the prequel novel, but it's been roundly slated. Apparently this is being picked up by Facebook Watch, but I don't think that I will be rushing to see it. I may listen to another series, but that may well be unlikely as it's jumping media format.
