Ellie Harper came to Crestwood University to reinvent herself and for a while, it was working. Gone was the awkward, prank humiliated girl from high school. In her place stood a sharper, prettier version who'd somehow caught the eye of Kyle Thurlow, popular hockey player. Their relationship was a secret his idea but tonight, her eighteenth birthday, he promised to change that. He didn't. What Ellie found instead was Kyle tangled with Lisa Voss the cheer captain, in Ellie's own bed on her birthday. Humiliated, furious, and a little drunk, Ellie does the most reckless thing she's ever done: she lets Nathan Black buy her a drink. Nathan Black, hockey team captain, campus legend, and the one man every girl wants.

They kissed before they knew they were family. Now, living under one roof, they’re trying to forget what never should’ve happened—while longing for it all over again. Lena thought moving into a new house in a new town with her mom was the worst thing that could happen until she found out that the mysterious, brooding boy she kissed at the pool was now her stepbrother. Lena found love where she shouldn’t have found love in the arms of her stepbrother, but he is off-limits as he goes from cold to hot, loving today, ignoring her tomorrow, but every glance, every touch, and every accidental moment alone stokes the fire between them. Living together with a wall separating their rooms, will they honor their parents' marriage and keep their hands to themselves? Torn between duty and desire, Lena must navigate secrets, scandal, and a house that’s far too small for forbidden feelings.
