Rock Hard Gargoyle

The series itself is called Possessive Monsters but it only sometimes came out in Grayson.
It's set in the real world, after the Wall hiding the supernatural has gone down and they're now out in the open. After crashing a wedding, Shelby is accidentally thrown into a world she didn't know existed until recently, she also discovers something about herself and takes it like a champ. There is chemistry between Grayson and Shelby and the plot is interesting enough.
