Really Valentine's Day was named after several Christian Saints by with the name of Valentinus. Some of these saints were imprisoned for performing marriages for soldiers who were forbidden to marry because their job was to go around and minister to Christians. They were not supposed to be married.
BUT who isn't a sucker for love??
(Isn't this heart donut cute? It's from a local bakery and it's half the calories of a regular donut!)
There is way more to the history of Valentine's Day, but the romance is what struck a cord with me as a writer. And I know readers love romance. Take the Fifty Shades of Grey series~every single woman reader (okay, not every single one....but a ton of them!) went goo-goo-gaa-gaa over them.
