Goodreads Recommendation

Goodreads makes recommendations for books they think may interest me as a reader based on a book or books I’m currently reading.

However, I think this algorithm needs some refining.

The 28th October recommendation was based on the book:

The Tyrannicide Brief: The Story of the Man Who Sent Charles I to the Scaffold by Geoffrey Robertson QC

and the book Goodreads recommended was

The Man who made Husbands Jealous by Jilly Cooper

I’m still trying to understand what connects these two books?
