Chameleon

Sixteen-year-old Samantha Ruiz has a lot on her mind. The crush who kissed her but changed his mind. The BFF who thinks Sam is in an abusive relationship. The Nazi-geneticist who wanted Sam dead but now wants her ALIVE. All this, and she's still dealing with a tendency to disappear into thin air. When Sam learns of her nemesis Helmann's Nazi-like plan to re-establish a Thousand-Year Reign, she's determined to fight him. Along with Will and Mickie, Sam flees to France to meet Sir Walter--their best hope for stopping Helmann's brave new world. Unfortunately, Sam isn't any safer in France. Someone invisible is following her, and now Sam must figure out how to hide from an enemy she can't even see.
