Wayward Haunt

A girl with a morbid ability...
In the middle of the centuries-fought war between casters and humans, teenage necromancer, Zaya Wayward, is sentenced to the filthy coal mines of Gosheniene for a murder she didn't commit.
Necromancy is outlawed magic, and Zaya knows that revealing the true killer, a wraith fuelled by violence and rage, will result in her own execution.
When Zaya is conscripted into service life at the Tarahik Military base, the ghost is waiting. Zaya's ability to see the dead is the key that could annihilate human existence, and sinister forces will go to unstoppable lengths to get it.
Determined to find the link between her past and a puzzle that threatens the world, Zaya joins forces with Captain Jad Arden, the pair propelled into a breakneck chase across haunted wastelands, desolate ruins, and ravaged cities. But Jad has secrets of his own, and Zaya's feelings for him could be her undoing.
One thing the wraith does ensure... the wrong choice will cost Zaya her life.
