I've just been alerted to the fact that you can, in fact, pre-order the Very Secret Sex Lives of Medieval Women right now on the Book Depository (which has free shipping!) It says the release date is July 30th, 2020 while I believe it will be available through Amazon on the July 14th, 2020, but if you don't mind waiting a week.. well, free shipping is great! It's also the special pre-order price as well!
If you're coming to the Abbey Medieval Festival 2020, I will have books with me if you'd like to collect in person. I might organise some kind of pre-order myself there in case I don't have many with me and someone misses out! I really have no clue how many to bring to Abbey. This is all very new and exciting!
