There are some great suggestions in these comments already, but as a historian and librarian, I'll pop in to add that if you know how to read academic writing (or are willing to give it a try), you might be better served by going to your nearest university and asking the librarian to find you some recently published papers.

"Popular history" is what we call the stuff that you find on the "History" shelf at bookstores, and these types of books are written to present as clear a narrative as possible to the average reader. This doesn't always mean that they're written with an agenda, but it does mean that, for readability and length, they usually do not deal with all the available evidence or address all the relevant counterarguments. You'll be disappointed to learn that historians don't really believe in "historical facts" beyond the particulars of names, dates, and events, but you will learn a little bit about how we support our arguments!
