Sometimes you get more than you bargained for when the party's over ... Last Halloween, Romy had a one-night stand with a stranger dressed as Darth Vader. Now she has a baby named Luke. But who is his father? Because though she and Darth shared their deepest, darkest secrets, they didn't swap names or numbers. While Romy is happy to raise Luke on her own, one day he'll need to know the truth about his father, and Darth deserves to know he has a child. There's only one problem. Luke's father knows things about Romy's past that she'd rather stay hidden - and finding him means she'll have to face the memories she's been running from. Just as she's about to give up on ever discovering Darth's true identity, an old flame arrives back in her life with secrets of his own. Could he be Romy's dark knight? Or is there another?
