Love 2 Hate U by Alexandra Silva

SEBASTIAN:
Man, Kate is the definition of cat lady. She’s all work and no play,
the stick up her peachy ass is lodged so far up there, she’s the star
of her own muppet show. Somehow, my baby sister’s landed me a
starring role. Now that we’re stuck together, I’m determined to put
the fun into Kate. It’s just too bad her sense of humor sucks harder
than she does. But I’m a patient guy, if I can crack code, I can crack
her. And I’ll take all the pleasure in it.
She can deny it all she wants, but I know she loves me and my jokes.

KATE:
Sebastian doesn’t take anything seriously. Life is one big dick joke
to him. So when Amelia, his sister and my best friend, tells me we
will be working together on an upcoming pitch… not amused. He
loves to rattle me. Everything he does drives me crazy.
He might think I love him, but I just love to hate him.
