Question: The book is fairly new, at most 4 years and it's the start of a series.
I know vampires were involved and that the bookstore was open at night but
that's about it.

> *Night Owls **book store** is the one spot on campus **open late** enough to help out even the most practiced slacker. The employees’ penchant for fighting the evil creatures of the night is just a perk…*

> 
> Valerie McTeague’s business model is simple: provide the students of Edgewood College with a late-night study haven and stay as far away from the underworld conflicts of her vampire brethren as possible. She’s lived that life, and the price she paid was far too high to ever want to return.

> 
> Elly Garrett hasn’t known any life except that of fighting the supernatural werewolf-like beings known as Creeps or Jackals. But she always had her mentor and foster father by her side—until he gave his life protecting a book that the Creeps desperately want to get their hands on.

> 
> When the book gets stashed at Night Owls for safe keeping, those Val holds nearest and dearest are put in mortal peril. Now Val and Elly will have to team up, along with a mismatched crew of humans, **vampires**, and lesbian succubi, to stop the Jackals from getting their claws on the book and unleashing unnamed horrors…

> Kathy McKenna was sure that the little Midwestern town of Oak Hollow would be isolated enough for safety, but the moment the black-clad stranger walked into **her bookstore**, she knew she was wrong. Raphael Cordova exudes smoldering power, and his sensual touch draws Kathy into a world of limitless pleasure and unimaginable dangers.

> 
> Oak Hollow was supposed to be neutral territory for Supernatural beings. Instead it has become home to an evil force determined to destroy them—and kill any mortal who gets in the way. As **leader of the North American vampires**, Raphael has always put duty first, but then, no woman ever enthralled him the way Kathy does. And as the enemy’s terrifying plan is revealed, Raphael’s desire could be a fatal distraction for all his kind, and for the woman he has sworn to love forever…

This one is probably the least likely, as it looks like the vampires are the focus of the series with the bookstore owner only showing up in this 2008 entry.
