Any in English sources (books/documentaries/etc) on the Kingdom of Georgia circa 1400s?

by AphTeavana

Most of the books in English that I find are about the country after USSR/Russian conquest, which isn’t very relevant to what I’m interested in seeing. I’m particularly looking for something on King Vakhtang IV and his father Alek I, the life of their noblemen, and the downfall of the Bagrationi dynasty near the end of the 15th century. I’ve been browsing the government website and the national library page for Georgia, but often find myself having to rely on google translate to actually read anything
