The Amber Crown

The king is dead, his queen is missing. On the amber coast, the usurper king is driving Zavonia to the brink of war. A dangerous magical power is rising up in Biela Miasto, and the only people who can set things right are a failed bodyguard, a Landstrider witch, and the assassin who set off the whole sorry chain of events. Can these three discover the real villain, find the queen, and set the rightful king on the throne before the country is overcome?
