I Hated You First by Rachel John

Sometimes love is war.

Clay… My best friend has held a grudge against his half-sister, Lauren, forever. It’s unjustified and ridiculous, but I have to take his side. Also ridiculous? How bad I have it for her.
My Lauren radar goes off the second she steps in the building. Did I mention we work together and her dad’s the boss? Yeah, she’s so off-limits I might as well start running now and never come back.
Except, her family is like family to me. So, I’ll do whatever it takes to stick around, even if she hates my guts.
Lauren… I date guys nothing like Clay on purpose. I will not let my old crush on him get the best of me. It’s going on the list of things I’ve outgrown and will deny ever having, like the Justin Bieber poster I used to keep on the back of my door.
It doesn’t matter that I’ve caught Clay looking at me like he’s a jewel thief and I’m a precious gem encased in glass. He’d never choose me over my brother, or his job, or his enjoyment in teasing me.
Avoiding Clay is easy, until the day I realize my dad’s asked for Clay’s help in checking up on my dates.
No stinking way.
