This story follows on from 'The Year of the Unicorn' as I realised when I began reading - although the characters were not named, I could tell that the woman having her baby in the shrine of Gunnora, at the same time as the mother of the narrator of this novel, is Gillan, the woman with powers in that novel, and her husband is Herrel, the Were, or shape shifter who can transform into a snow leopard. They come back into the novel much later.
I also realise on doing this review that I've missed out a couple of volumes in this second Witch World series, book 0 and book 1 - however, I don't think it prevented me from understanding or enjoying this one. Briefly, Heroise, the protagonist's mother, goes to the shrine to have her baby believing it will be a son and through him she will be able to rule, as their land follows the custom of the sister's son of the ruler inheriting. The baby is a girl - but a ready solution presents itself as Gillan is in the room next door having her baby which they realise is a son. The mother's nasty wise woman sidekick Ursilla puts Gillan and her midwife into an entranced sleep and makes them forget so that when they wake up they think the baby girl is her own child.
However, things don't work out as Heroise hoped, as the son, whom she names Kethan, is not the malleable tool she and Ursilla hoped. He is too independent and he also faces enmity within the keep because Heroise's sister-in-law hates him and wants her own son Maughus to succeed the father, against custom. Kethan grows up in an atmosphere of tension and hatred, although this is character building in the long run. His time of trial comes when he is betrothed to Maughus' sister, and her mother gives him a gift to commemorate it - a belt he had already been drawn to when a mysterious trader visited the keep. The belt has the effect of turning him into a pard - a big cat - probably because it brings out his innate gift from his real father, Herrel. Everyone, including him, assumes it is a curse laid on him by the belt. The intention is either to kill him as an animal, or else to denounce him as a thing of the Dark. So he has to go on the run, unable to turn back into his human form, and pursued by multiple enemies.
It is quite a short book in comparison to some of the other Witch World novels and a quick read. It isn't outstanding, but I enjoyed it nevertheless, with the suspense as to whether Kethan would prevail, whether he would learn who his real parents are, and whether he would come into his true heritage. So I would award this a page turning 3 stars.
