Irish is the 5th book in the Reed Security Series and should be read in order.

Derek
I watched her watching me. She followed me around the grocery store, choking on a grape when she tried to talk to me. It was so damn cute. So, I asked her out on a date, and that ended badly. I tried again, but I kept saying the wrong thing. Who knew that telling a woman she had a juicy ass was a bad thing? I thought it was a compliment. I swear to God! And don't get me started on how quirky she is. And she always has her nose stuck in a damn book. But none of that would stop me from being with her. Not even when I found out that she thought I was an actual superhero.

Claire
Okay, I might have stalked him through a grocery store. What can I say? He was so hot, and I just couldn't help but stare at him. It wasn't my best first date, but it probably wasn't my worst either. And no matter what crazy things I do, it never seems to really push him away. But there is this one tiny, little detail that's been bothering me. I think he's Superman, red cape and all. Seriously, there are some strange things happening, and he's always at the epicenter. There's no way he's not a superhero. Okay, maybe I've been reading too many books.
