Goodreads description:
Audrey Whitticomb has nothing to fear. Her mother is the superhero Morning Star, the most deadly crime-fighter in the Twin Cities, so it's hard for Audrey not to feel safe. That is, until she's lured into the sweet night air by something human and not human--something with talons and teeth, and a wide, scarlet smile.
Now Audrey knows the truth: her mom doesn't fight crime at night. She fights Harrowers--livid, merciless beings who were trapped Beneath eons ago. Yet some have managed to escape. And they want Audrey dead, just because of who she is: one of the Kin.
To survive, Audrey will need to sharpen the powers she has always had. When she gets close to someone, dark corners of the person's memories become her own, and she sometimes even glimpses the future. If Audrey could only get close to Patrick Tigue, a powerful Harrower masquerading as human, she could use her Knowing to discover the Harrowers' next move. But Leon, her mother's bossy, infuriatingly attractive sidekick, has other ideas. Lately, he won't let Audrey out of his sight.
When an unthinkable betrayal puts Minneapolis in terrible danger, Audrey discovers a wild, untamed power within herself. It may be the key to saving her herself, her family, and her city. Or it may be the force that destroys everything--and everyone--she loves.

This one sounds really awesome, sort of futuristic but also rooted in some kind of lore. I need to know more about the Beneath and what exactly the Harrowers are. I'm really curious about Audrey's powers and that Leon guy too ;)
Have you heard of Dark Star before? What are you waiting for this Wednesday?
