The pain merchants - Janice Hardy

Nya has a secret she must never share.
A gift she must never use.
And a sister whose life depends on both.

This astonishing debut novel is the first in the epic dystopian fantasy adventure trilogy, THE HEALING WARS.

Fifteen-year-old Nya is one of Geveg's many orphans; she survives on odd jobs and optimism, finding both in short supply in a city crippled by a failed war for independence. Then a bungled egg theft, a stupid act of compassion, and two eyewitnesses unable to keep their mouths shut exposes her secret to the two most powerful groups in the city: the pain merchants and the Healer's League. They discover Nya is a Taker, a healer who can pull pain and injury from others.

Trouble is, unlike her sister Tali and the other normal Takers who become league apprentices, she can't dump that pain into pynvium, the enchanted metal used to store it. All she can do is shift it from person to person, a useless skill that's kept her out of the league and has never once paid for her breakfast.

When a ferry accident floods the city with injured, the already overwhelmed Takers start disappearing from the Healer's League and Nya's talent is suddenly in demand. But her principles and endurance are tested to the limit when her talent turns out to be the only thing that can save her sister's life.
