This is the story of Tenar, who is said to be a priestess reborn. As a result, she is taken from her family at a young age and brought up in a temple complex, taught to be the mistress and guardian of the Undertomb and Labyrinth. No-one else is allowed in all the dark places, on pain of death. The rest of this review is at Comfy Chair, where I get paid for it.
Free sample (when, at the age of six, Tenar has taken up her role as the reincarnated priestess):
The child said nothing. Manan turned around and went away. The glimmer died from the high cell walls. The little girl, who had no name any more but Arha, the Eaten One, lay on her back looking steadily at the dark.
Rating: G, and recommended for any age that likes reading.
