Vulnerable by Amy Lane

Working graveyards in a gas station seems a small price for Cory to pay to get her degree and get the hell out of her tiny town. She’s terrified of disappearing into the aimless masses of the lost and the young who haunt her neck of the woods. Until the night she actually stops looking at her books and looks up. What awaits her is a world she has only read about—one filled with fantastical creatures that she’s sure she could never be.

Publisher Description

And then Adrian walks in, bearing a wealth of pain, an agonizing secret, and a hundred and fifty years with a lover he’s afraid she won’t understand. In one breathless kiss, her entire understanding of her own worth and destiny is turned completely upside down. When her newfound world explodes into violence and Adrian’s lover – and prince – walks into the picture, she’s forced to explore feelings and abilities she’s never dreamed of. The first thing she discovers is that love doesn’t fit into nice neat little boxes. The second thing is that risking your life is nothing compared to facing who you really are – and who you’ll kill to protect.
