Dragon Bones (Red Princess #3) by Lisa See

In a magnificent land where myth mixes treacherously with truth, one woman is in charge of telling them apart. Liu Hulan is the Inspector in China’s Ministry of Public Security whose tough style rousts wrongdoers and rubs her superiors the wrong way. Now her latest case finds her trapped between her country’s distant past and her own recent history.

The case starts at a rally for a controversial cult that ends suddenly in bloodshed, and leads to the apparent murder of an American archaeologist, which officials want to keep quiet. And haunting Hulan’s investigation is the possible theft of ancient dragon bones that might alter the history of civilization itself.

Getting to the bottom of ever-spiraling events, Hulan unearths more scandals, confronts more murderers, and revives tragic memories that shake her tormented marriage to its core. In the end, she solves a mystery as big, unruly, and complex as China itself.
