Touch of Power, Avry is all of those things. She has the magical ability to heal people by taking on their illnesses or injuries. She was apprenticed to the Healer's Guild shortly before a plague broke out. The problem was any Healer who tried to cure a plague victim always died. When they stopped trying people turned on them and hunted them down. Even though Avry was only an apprentice they came after her too. She has survived by running and hiding, but her desire to heal always compromises her identity.
One day her luck runs out and she gets caught before she can leave town. While awaiting her execution, a band of men break her out of jail. The price for her rescue is using her ability to heal a sick Prince. This is just the start of Avry's problems. There are multiple villains, betrayals, lots of intrigue, and I loved every second of it.
