Titles in Deryn Lake's John Rawlings historical mystery series go on sale at $0.99/£0.99 pretty often, often enough that I don't post them any more.
However, now two omnibuses (four books each) have dropped to $0.99/£0.99 each, as Kindle Countdown deals, with not much time left. And $0.25/£0.25 if you need them all seems good enough to post. Also note that the prices aren't going all the way back up right away, but to $1.99/£1.99 for a while, which is still a pretty good deal.
Sadly the first omnibus is still sitting at $5.99/£4.99 (but available through KU if you have that), so this won't help you read in order if you wish.
John Rawlings Investigates (Part Two), contains:
- Death in the Peerless Pool
