Ravenden by Julie Trettel

Life is never easy being the outcast.

Gia’s red hair and lack of powers set her apart from every other raven shifter witch in existence, and not in a good way. Shunned by her Flock, still living with her parents, and working day in and day out as a waitress, she longs for a change.
David is a mimic, one of a kind. Being different isn’t always a good thing. The only time he feels like he’s fitting in is when he’s pretending to be someone else. Alone, jaded, and always hiding, he just wants someone to see him for who he really is.
Be careful what you wish for.
An unfortunate mishap changes everything as Gia finds herself lost inside a world of fairytales and nightmares unable to discern what is real and what is make believe. When David sees her from across the room, he is drawn to her in ways he doesn’t understand, but the silent raven spirit within him awakens and immediately recognizes her as his one true mate.
As truths are unraveled and favors are called, it’s no longer safe for Gia and David inside The Diner. Can they work together to get out before it’s too late? Or will they be trapped in The Diner forever?
