And the #4 seller in Medieval History (any kind of history, not just church history), too.
In a pretty rare circumstance, I do know how long the markdown on the ebook will (or is supposed to, at least) last. The price goes up to $3.99 at about midday Eastern time on Sunday. If you're reading this after that time, well, you might be outta luck.
The Amazon ratings on this book are a little weak (for my tastes), but there's really not enough of them to get a true picture. At GoodReads they're about the same (but there are less of them), but GoodReads raters tend to be . . . . how shall I say this nicely . . . . less charitable with their ratings than Amazon reviewers.
Don't hesitate to at least give this book a look (I just made that up.

) because it is self-published. The author has at least one other book on the Knight's Templar for sale at Amazon, in addition to a novel there, set in Medieval times. He has also published research works on Classical Latin poetry and created software tools to facilitate the study of ancient languages. He also translated Medieval and Classical prose and poetry. But I could do those things too, if I wanted to. Well, okay, I'm lying, I couldn't.

Book Description
The Order of the Knights Templar, founded in the aftermath of the First Crusade, was one of the most powerful organizations in history. Only after European rulers lost much of their resolve to keep Palestine under Christian control the Order suffered a dramatic downfall initiated by King Philip IV of France. In every region of the world where the piebald flag of the Knights Templar once flew above castles and houses there are myths and curious accounts of those ancient times. England, Scotland, Ireland, France, Spain, Portugal, Israel, Egypt, Switzerland, Italy, Germany, Poland, Czech Republic—all these lands have their own stories to tell. The new book by A. A. Grishin combines the most fascinating stories ranging from mainstream historic narratives to local folklore, highlighting the Templars’ valor and influence, as well as popular beliefs in their mystic knowledge, cruelty and macabre transgressions. Many of these legends have never been published in English.
