The White Lady is book 4 in the space fantasy series, Voidhawk.
The people of Kelios have an unlikely group of saviors in a cursed priest, a confused sorceress, and a woman with a damaged soul trapped in the body of a teenage girl.
The three members of the Voidhawk's crew came to Kelios seeking council with an powerful race of beings called the Fayer. Along the way they run afoul of the unholy army of The White Lady and vow to stop her. The only problem is that the answers to Bekka's problems may come from the very being they're determined to destroy.
