Whatever Else — J. Kathleen Cheney

Maia is a young woman with only a small gift: the ability to watch others from afar. To cement a treaty between two clans, she married Arras, a young man she's known most of her life. But when her brother comes to visit, he reveals a shameful secret that leaves Maia questioning everything she believes about her husband. Now she must use her small gift to determine the truth of her brother's claim...and decide whether to stay at her husband's side or flee him.
