Tokyo Heist — Diana Renn

When sixteen-year-old Violet agrees to spend the summer with her father, an up-and-coming artist in Seattle, she has no idea what she's walking into. Her father's newest clients, the Yamada family, are the victims of a high-profile art robbery: van Gogh sketches have been stolen from their home, and, until they can produce the corresponding painting, everyone's lives are in danger--including Violet's and her father's.

Violet's search for the missing van Gogh takes her from the Seattle Art Museum, to the yakuza-infested streets of Tokyo, to a secluded inn in Kyoto. As the mystery thickens, Violet's not sure whom she can trust. But she knows one thing: she has to solve the mystery--before it's too late.
