I recently finished Mrs. Queen Takes the Train. It was a fun, light listen: a fictional account of Queen Elizabeth sneaking out of the palace on an adventure. She does yoga in it!!!
A previous listen I should mention is Julian Fellowes’ Belgravia. I thoroughly enjoyed it; some people complained that it was just Downton Abbey repackaged (I don’t agree). Not particularly complex, so a good thing to knit to.
Lastly, Pride and Prejudice, read by Rosamund Pike. I’ve read the paper book a billion times, seen all the movies and I still cried buckets of joy at the end. Utterly brill.
