All but one (
Death at the Devil's Tavern) of the first 12 titles in Deryn Lake's John Rawlings series are priced at $0.99 each at Kindle US as of now. Most are on US Kindle Countdown deal for about 3 1/4 more days, a few are long term at $0.99.
I'm providing a link to the "series" webpage at Kindle US, which only includes the first 12 titles, now published in e-book by Endeavour Media, and not any of the later titles in the series (another publisher). But, none of those are $0.99 anyway.
You can just take a look yourself and pick out any that you might want. (You may need to click on "show all" at the bottom of the page to see all 12.)
