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.
