All Fall Down by Ally Carter [Book 1 in the Embassy Row series]
Since her mother died three years ago, sixteen-year-old Grace has been living with her ambassador grandfather in Adria, Italy, where he is currently placed. The problem is that she is the only one who believes that her mother was murdered. Her grandfather’s role and her home among diplomats from all over the world mean that Grace is supposed to behave in a certain way, and that means not trying to solve her mother’s supposed murder. And all the politics around her mean that it’s hard to know who to trust while she intends to go on doing just that. Grace knows that there’s more at stake than closure for her mother’s loss; in the politically-charged world around her, potential danger to the ambassadors could have ramifications for entire countries.
