Varus: Heartlight (Varus, #1)

Ionia. A land of magic. A land of balance. A land of light. But not always a land of peace. Just as there are creatures within Ionia who seek to upset its order, so too are there those who fight to preserve it; Arrows of Protection, hunters of monsters. Valmar and Kai are two such hunters. But not all monsters can be defeated with bow and steel. And not all darkness can be so easily banished by the light.
