The Finest Challenge (Finest Trilogy, #3)

Kalantha has successfully rescued her brother from the shadow of the evil bishop's bellicose influence, but now finds herself cut off from both him and her Finest protector, Gallant Stallion. All three must race against the clock to curtail the unnecessary war that the Bishop's minions have engineered. And, still lurking in the shadows and prowling the night skies is the avian menace whose dreams of a carrion-strewn countryside can still come through if their equine nemesis is neutralized.
