Nancy Mitford (that's her on the book cover above). If you like Downton Abbey, you might like reading Mitford's books, too. British upper class wit and silliness, I have read that what she wrote was based on people she knew. It is quite entertaining. I am currently in the middle of Pigeon Pie, and enjoying it, as well.
Speaking of Downton...Season 5 if off to a great start, don't you think? Fun stuff! And then Outlander starts up again in April.
In the meantime, I will be reading a book series I just found out about over at Some of a Kind for today's Turn the Page ... Tuesday. Check it out!!
