Palace of Doom (Grave Robbers' Chronicles)

It’s a grave-robbing reunion when Fats, Poker-face, Panzi, and Uncle Three’s long-suffering nephew find themselves on a train headed for a mysterious, mythical palace in a world of glaciers, avalanches, and blizzards. They have no idea why Uncle Three has sent the message that brought them all together again but they soon discover that they aren’t alone in their search. Their femme fatale adversary, Ning, is on the same trail, with a team of foreigners—and quite possibly a hostage—Uncle Three.
