I read The World According to Clarkson by Jeremy Clarkson
No overarching theme, each chapter is a story in itself. Non-fiction, beyond the fictitious parts he comes up with.
He wrote real interesting things about migration. How human traffickers using fast motorboats to ship migrants from Albania to Italy, and that it's a great business for some, and that lots of migrants are forced to do crime for this mafia to so he can pay for his fee and save his family from being sold as slaves and prostitutes, and that the Afghans are coming. Elsewhere he also mentions how migrants try to get through the Channel into England.
The book wasn't written in 2025, neither in 2015 at the start of the "migration crisis", but in 2001. This raises the question: when did this crisis start actually?
