The Grove of the Caesars is the eighth and most recent (until the new one comes out in July) in Lindsey Davis’s Flavia Albia series. It’s £0.99 at Kindle UK right now, March 1, 2021. I’m not sure if this is part of the new monthly Kindle UK sale, or just that UK thing where they put most-recent-in-series titles at £0.99 for a brief time every now and then. So definitely grab it now if you want it – it has been up at £5.99 or more until now. I’ll update later once I have time to look at the monthly sale.
