Two of the three books in Chris Lloyd’s Catalan series are $1.99 each right now in the US, and all three are £1.99 each at Kindle UK. Not sure why the difference, but maybe the second one will still drop in the US, so I’m giving series links for easy price-check.
The books are: City of Good Death, City of Buried Ghosts, and City of Drowned Souls. I haven’t read any these but they look pretty interesting.
