Death's Purgatory

Death, the ruler of the Eternal Realm, bearer of the pain of all Beings, dead and living, sees no importance in life.
Avery McKeown, a trans teenager with a distain for death, dies... just at the wrong time.
Avery is faced with the literal ghosts of her past. And Death is faced with betrayal. As heinous ideologies are unearthed, and more still-living people start dying, the two must dig deep inside themselves to find an appreciation for both life, and death, in their entirety.
Who's behind the killings? What if they're right to do so.
