Nikki has a lot going on at the moment. She's the best sound engineer and mixer at XY Records, she's working on a super-secret project with a pop megastar, and holding the busier-than-usual studio together. The last thing she wants or needs is her ex-fiancé to start working in the studio over the summer. She's over it-him. Obviously. Being ghosted has that effect. But working near someone she used to love has made her life that much more complicated. Andre has it all figured out. Two and half years ago he had no idea what he was doing when he walked away from the love of his life. But time has given him perspective, and he's grown up-which is why this paleontology professor is working part-time at his ex's recording studio. Because he wants to make amends. And maybe win her back. Will Nikki give him the chance he thinks he's ready for? Or will it be her turn to walk away from him? All Mixed Up is book #8 in the Common Threads series, Seduction in the City World, which is part of the Penny Reid Book Universe.
