I’ve read almost all of the books in Deanna Raybourn’s Lady Julia Grey series, and have quite liked them. They do go on sale individually pretty often, but now (Feb 21, 2021) here’s a box set of the first three for $1.99 at both Kindle and Kobo US. If you don’t already have any of these, and want to give this nice historical series (with a touch of romance) a try, this is a great price for the three!
Titles in the box set include: Silent in the Grave, Silent in the Sanctuary, and Silent on the Moor.
If you missed out on the box set a while back, the first book, Silent in the Grave, is now on sale individually in the US for $1.99. And it seems to be semi-long-term at 0.99 in the UK.
