PS. I suggest spoilers as chapters 8 forwards (7 is the day when the hunt sets out)
A book with very good rereadability. Moral about racism, but doesn't preach. Plot centres around a cursed collar.
Minor characters, with relations to Ayna, Gair and Ceri: parents Gest (chief of the Garholters?) and Adara. Grandparent Og. Cousin Ondo and his two "henchkids" Scodo and Pad. Uncle and aunt Orban (chief of the Otmounders) and Kasta. Everybody a species called Lymen.
