One Kiss from the King of Rock by Ainslie Paton

Evie Tice won’t kiss her ex, Jay Endicott, ever again. But she wants to. Burns for it. Half the adult population of the world does, because he’s a rock god who can apparently light up the stage. She wouldn’t know. When he quit on her, she made sure to block him from her life and stick to easy breezy hook-ups.
But Jay is back, sexier than ever, with the first leg of his global tour and her brothers’ band opens for him. As their social media manager, Evie can’t avoid Jay, but she can use him, to get off and get even, like he once used her.
There’s just that one little no kissing issue. Because if Evie kisses Jay, she’s going to fall in love with him all over again.
