Anastasia Phoenix has always been the odd girl out, whether moving from city to international city with her scientist parents or being the karate champ who speaks four languages-and most definitely as the orphan whose only sister is missing, presumed dead.

When Anastasia finds her sister's bathroom covered in blood but with no body, she's the only one who believes Keira might still be alive. The suggestion that her devoted sister and legal guardian is the victim of a random, dead-end homicide is too much for Anastasia to bear. If the police refuse to investigate her sister's disappearance as a missing persons case, then Anastasia will have to do it on her own. Because nothing is as it seems, and Keira's behavior the last few weeks isn't making sense.

Anastasia is sucked into an international mystery, tracking her sister across continents with the help of a mysterious Spanish boy she's starting to fall for. But Anastasia can't shake the feeling that someone else is pulling the strings.
