Chronicles of Khaldun: Arctic Death, Infinite Night
Sister to Khan Chago, Khatun Javach has been erased from the histories in the intervening centuries. Unbeknownst to the rest of Isiksivik, she has survived for decades in a magic jar, waiting for someone to disturb her tomb and return her to the world.
While she has succeeded on that front, she has not found the world she sought: her brother now rules as Khan Yemur, and his magical ambitions have overtaken anything she could have conceived back in her mortal days.
When she returned, she did so in the body of Laurie Weathermay-Foxgrove. She has since disappeared with the body and her magic jar to parts unknown.
