It Was Always You by Judy Corry

Sixteen-year-old Lexi Stevens has never been kissed–never even been asked on a date. So when she humiliates herself in front of her crush and her brother’s best friend offers to be her fake boyfriend for the week to make her crush jealous, she doesn’t know if it’s the stupidest idea ever, or a dream come true.

When Noah Taylor’s abusive stepdad kicks him out of the house, the last thing he needs is for anyone at school to find out–not even his best friend. But when his new “girlfriend” discovers he’s homeless and lets him sleep in her closet, he starts to wonder if he’s found someone he can confide in after all.

Soon Noah and Lexi are putting on a big show in front of the whole school while sneaking around behind her overprotective father’s back. It isn’t long before feelings develop, and it becomes harder and harder to discern between what’s fake and what’s real.
