@mattlewishistory.bsky.social and @goingmedieval.bsky.social, thanks for this episode. @tamzen.bsky.social and I listened to it over dinner while enjoying cider from Posterity Ciderworks, which to us is like what we used to get when we'd visit Devon.

I picked up a brace of copies of Oathbreakers arrived (one to read, one to give away) from my local bookstore. Thanks, @profgabriele.com and @lollardfish.bsky.social !
