Nomansland by Lesley Hauge

Keller is a Novice Tracker. She lives in FoundLand, a country of all women. The world has changed, and while a few items of the Old People exist, most of them are gone. The materials from the Old People must be purged from their area, to avoid the catastrophe which caused the earth's destruction so many years ago.

But Laing finds a hidden cave of forbidden items and Keller can't stay away. The more she tries to resist, the more often she risks getting caught. The more she learns about the Old People, the less she believes what she's always been told.

An interesting premise. I enjoyed the story and Keller is a likable character. A few characters were not so fleshed out, but it didn't detract from the story. Lots of questioning authority and adventure, along with human nature.
