The Wild Road. The Burning Crown, #2

The second novel in Michelle West's The Burning Crown. THE WILDERNESS IS WAKING Stephen has never left the kingdom of his birth. But the possible cure for his huntbrother's shattered memories cannot be found in Breodanir. It might be found in the distant South. If Nenyane's road leads to the South, Stephen will follow. The lord of the golden fox wishes to speak with Stephen before he travels South.
She dwells in the heart of the empire, home to Meralonne APhaniel and Kallandras of Senniel, and it is through Averalaan that safe passage to the Dominion of Annagar can be found. The road to the empire passes through towns that have existed for longer than Breodanir itself: the Free Towns. The Free Towns have never fallen, although they are possessed of no armies, no walls. Stephen and his party arrive in Hansleigh to festivities and carnival performers in the streets: the circus is coming to town.
Theirs is a command performance. Every living person in the town is expected to attend, as if attendance is a matter of life and death. It is. To survive, the hunters must find a missing person before the circus-and all of the townspeople-are lost forever to the forces of the Lord of the Hells.
