Currently reading the Chronicles of St Mary’s series. I’m on book 10, which is the last one that I own, but I’ve really enjoyed the series so will definitely pick up the rest at some point.
It’s a series about historians who time travel to document historical events, so there’s an accurate telling of the story rather than things being disputed. It often ends up going wrong though. It’s rather light-hearted (apart from book 8 where everything goes a bit serious), and the humour is great. Similar humour to Terry Pratchett’s books, I would say, though I haven’t read loads of his work.
