Series information from author's website.

Trained in warrior magic after the murder of her parents, a girl with a star-shaped birthmark is prophesied to be the downfall of a tyrant king, but the boy she falls in love with owes his loyalty to those hunting her.

Gul has a star-shaped birthmark on her arm, and in the kingdom of Ambar, girls with such birthmarks have been disappearing for years. Gul's mark is what caused her parents' murder at the hand of King Lohar's ruthless soldiers and forced her into hiding. When a group of rebel women called the Sisters of the Golden Lotus rescue her and train her in warrior magic, Gul wants only one thing: revenge. Cavas is about ready to sign his life over to the king's army. His father is terminally ill, and Cavas will do anything to save him. When he meets Gul in the capital's bazaar, he becomes entangled in a mission of vengeance-- and discovers a magic he never expected to find. But Ambar Fort is a world with secrets deadlier than their own.... -- adapted from jacket.
