If We Kiss by Rachel Vail

Charlie Collins has never been kissed.

She’s never been in love, either. Charlie’s beautiful best friend, Tess, has kissed three boys and has loved each one of them. Then Charlie unexpectedly finds herself falling for Kevin, and she’s in a mess of trouble right away. For one thing, Tess is in love with Kevin. Even worse, his father seems to be dating Charlie’s mom, who suddenly can’t stop smiling. With no one to confide in, Charlie has to figure this one out for herself. But even as she tries to pull away from Kevin, she can’t stop wondering, What would happen if we kiss?
