You would think, by now, that Lara would be a little less trusting of people who make special requests and seem to not be telling her everything. As usual, this client's secrets nearly got Lara killed, and it got her mixed up with some very dangerous people.
She is asked to purchase one of a set of three Chinese nesting boxes, but before she can do so it's stolen right in front of her. When the box shows up in China, her deceased friend's husband asks her to try once again, even though the antiquities laws will not allow the box to leave China, no matter who purchases it. Apparently, the goal is to reunite the set and gift it to the Chinese government to keep it out of the hands of private collectors who would squirrel it away from public eyes.
Needless to say, there's a lot more going on than Lara initially realizes, but she's smart, if a little foolish, and starts to put the pieces together.
The backstory about the boxes and their original owner is bittersweet, and will stay with you for a long time.
