My rating: 2 of 5 stars
Summary: When PR pro Anna Wallingham gets dumped by her last client, she finds herself running out of options in LA, where looks trump experience. Desperate to prove she is still relevant, the fiftysomething accepts a shady job offer from Pierre Barton, secretive billionaire owner of Barton Pharmaceuticals. Isolated in a facility outside London, she agrees to test a new top-secret product guaranteed to make her look thirty years younger. Anna is starting to look on the outside the way she feels on the inside: ageless. But she soon discovers that her predecessor died under mysterious circumstances, leading her to research just who stands to gain—and lose—with this miraculous product. When Pierre drops dead in front of her, she takes off on a dangerous journey across Europe hoping to stay alive long enough to uncover the truth.
