Valiant Valkari (The Moonflower Chronicles)

A plague is ravaging the land. Sweeping down from the Barbarian Wastelands, its victims succumb quickly and die in agony - only to rise again from their graves and spread the cursed pestilence further. Tasked with searching for the missing witch Sarah, who maybe the only one able to find a cure for the plague, Merick and Keera set off north to find her. Unaware that this plague is a prelude to the start of an invasion by a sworn enemy of all the Valkari, and with an ancient prophecy predicting their future, the path ahead is fraught with danger at the best of times. And at the worst times - It's deadly!
