Jorian Xilarsky, together with his own, goes to the capital of the empire Penembey south of Novaria, where he will have to fix the clock on the tower of Kumashar, the great lighthouse of Iraz. Many years ago, they were installed by his father, the talented watchmaker Evor. But in a foreign country, the former king will face a new test - a meeting with the leader of mercenaries and the revolutionary army Ishbahar. It will take not only guile but luck for Jorian to just get out of here alive, let alone save the city and seize on the miserable hope of recapturing Estrildis's beloved wife with Karadur's flying bath.
