Hidden Sun

Rhia Harlyn is a noble in Shen, one of the dozens of shadowlands which separate the bright, alien skyland. She has a missing brother, an unwanted marriage proposal and an interest in science considered unbecoming in her gender. Her brother’s disappearance coincided with a violent unsolved murder, and Rhia impulsively joins the search party headed into the skyland - a place whose dangers and wonders have long fascinated her. The dangerous journey brings her into conflict with a young rebel stuck between the worlds of shadow and light, and a charismatic cult leader who believes he can defeat death itself.
