Kindar's Cure — Michelle Hauck

Princess Kindar of Anost dreams of playing the hero and succeeding to her mother's throne. But dreams are for fools. Reality involves two healthy sisters and a wasting disease of suffocating cough that's killing her by inches. When her elder sister is murdered, the blame falls on Kindar, putting her head on the chopping block. A novice wizard, Maladonis Bin, approaches with a vision-a cure in a barren land of volcanic fumes. As choices go, a charming bootlicker that trips over his own feet isn't the best option, but beggars can't be choosers. As Mal urges her toward a cure that will prove his visions, suddenly, an ally turns traitor, delivering Kindar to a rebel army, who have their own plans for a sickly princess. With the killer poised to strike again, the rebels bearing down, and the country falling apart, she must weigh her personal hunt for a cure against saving her people.
