The Necromancer’s Daughter by D. Wallace Peach

Barus, a healer and dabbler in the dark arts, is forgotten in the dying queen’s chamber. He spirits away her stillborn infant and breathes life into the wisp of a child. Raised as the necromancer’s daughter, Aster, too, learns to heal death.

As the king’s life nears its end, he defies the fiery Red Order and summons his only heir. For his boldness, he falls to an assassin’s blade, and the Red Order rides, vowing to cleanse the land of evil.

To save her father’s life, Aster flees into a wilderness of dragons and barbarian tribes. Unprepared for a world rife with danger and unchecked power, she must choose whether to trust the one man most likely to betray her—her enemy’s son.
