Dusk or Dark or Dawn or Day by Seanan McGuire
Dusk or Dark or Dawn or Day is a love letter to life through talking about death. A ghost working towards her dying day by helping others, a few minutes at a time. Full of care for people and places; calm and haunting.
It's about death and suicide from the perspective of a ghost who's slowly earning her way to passing on after dying too soon. I like this version of ghosts and witches and I appreciate the way it cares about cities and small towns in different ways. It's a pretty short book so avoiding spoilers is tricky, but it builds a really complete world with just a few locations and a minimal cast of characters. It deals heavily with themes of suicide and death, so please take care of yourselves.
CW for suicide, death, imprisonment.
