Sands of Betrayal — Jason Halstead

Alto's choices have led him through ruin and victory. His friends and his enemies are among the most dedicated the world has ever seen. From farm boy to champion, Alto has excelled where no one else has dared to venture.

Now the young Thane must fight through the broken remnants of the Order of the Dragon and the city of Mira to rescue his imprisoned sister. She's being held for the death of her husband, a minor royal who married her under false pretenses. Alto must save her and find a way to abort the massing armies that threaten to overwhelm the northern nations.

But first his enemies give him a choice, save the woman he loves or save his sister. Only he can decide who must die so that the other may live.
