We'll get to watch the Viscount as he, under familial pressure, sets out to find a wife. But a woman named Kate (played by Simone Ashley) uncovers his true intentions, arguments arise, banter comes in hot, and tensions soar.
The second season is based off of Julia Quinn's books, this one in particular being The Viscount Who Loved Me. And because we have a while to go before we get to binge, you have plenty of time to read the book beforehand.
