To Heal a Broken Planet — Janice Clark

Mix a regressed society, a former space colony recovering from a long ago disaster, with an off-world group searching for new medicines. Add the indigenous, telepathic "little people" to the mix, throw in a society of psychic healers, and maybe a cat with interesting friends. Narrow the focus to a special child who may or may not be the child of prophecy but at least has connections to all the others. The fate of her world may depend on the child learning the secrets of her past-if the darkest secret doesn't catch up with her first.
