Part fantasy, part modern day adventure in China, the story is a mystery and a treasure hunting quest. Love the setting, love that the reason the treasure is still hidden is because no one seems to remember that it exists outside of Mia's family (which makes it slightly more believable). Good characters, and while Mia definitely has some of the ol' middle grade angst, it doesn't overshadow the larger story. I also like that the villain is acting out of despair, which is compassionately dealt with, but not forgiven. I also like how Mia is testing her independence and finding out how to rely on herself. I think it's astonishing that one can have a 500 year old mystery and the landmarks/clues are still there. I also loved the almost abstract map. Altogether pretty cool. ( )

Mia is visiting China with her mother, older brother Jake, and Aunt Lin. Mia feels left out and awkward - she's shy and quiet, prefers to read and dream while her mother and brother are outgoing, ambitious, and successful. Both Mia and Jake are uncomfortable around their unfamiliar relatives and don't really understand their mother's urge to visit her childhood home. Mia feels like the only person who understands her is her historian Aunt Lin.

When Lin disappears, leaving only a cryptic note behind, the rest of the family says it's "just Aunt Lin." But Mia is sure that's not true. Aunt Lin promised her she'd never go away without telling Mia, not after their father left and never came back. Mia is sure there's something going on - and it's all connected to the emperor's treasure that she and her aunt have talked about so often. But they're not the only ones searching for it and danger is getting ever closer...

This is as much a nuanced portrait and a family and the way history and culture affects people as it is an exciting adventure and mystery. Mia is frustrated that Jake seems to fit in better in China - even though she's the one who speaks better Mandarin - because he can blend effortlessly in with the local boys and play sports. The after effects of the Cultural Revolution are referenced in a way that's both relevant and understandable. Mia vaguely knows that this is something that had a huge effect on her family, but she can't really grasp the full concept.

The mystery is equally intriguing, blending clues and history together as Mia and Jake travel to different spots to solve the riddles and clues, explore the map, and eventually discover the treasure - and Aunt Lin.

Verdict: This is an exciting adventure that is sure to grab the attention of mystery fans but it will also resonate with children whose parents immigrated from another country and those readers who want to look into a different experience or culture. Recommend to fans of Thanhha Lai, Blue Balliett, and Christina Diaz Gonzalez.
