E.B. Roshan

Southeast Europe, circa 900 A. D. Kurosh is in desperate circumstances: a single mistake could cost him and his family their lives. His father, Rayis Sikandar, is among the most respected of the nomadic warlords, but he is very ill. If the Rayis dies, Kurosh must lead the clan in his stead-assuming he can prove his strength and escape his rival's schemes. Oday, the privileged heir of nobility and only Christian in his clan, joins his servants for the annual cattle drive.
However, when he wakes one morning, his mind is full of a strange and vivid dream, a dream that convinces him God has given him power to be a Healer. When the two boys meet unexpectedly, underlying tensions within their clans rise to the surface, and both must decide what is worth sacrificing for.
