If you want to learn about the Picts, this is the book to go for. But I'd only recommend it if you're a history buff, because it's heavy on wars and names and the writing style a little dry. I wanted to learn more about the normal folk, but it seems like there isn't a lot of data just yet. There is a bit of this in the afterword of the 2016 edition.
I may have or have not ordered another book by this author 😉
