Undoing Cycles - Hotel Between Worlds, #1

Previously published as 'Undoing Cycles' by Noct Moll. Ignorance is bliss, knowledge is suffering......until you remember your past. Seventeen-year-old Lisa manages the laundry at the hotel between worlds. Has always managed, in the eternity stretching backward. Will always manage, in the eternity stretching forward. In other words, forever. Because that's what the worker-residents of the hotel do for the recently-dead.
But Lisa's "forever" ends when a mysterious guest awakens terrible memories. Buried memories. Memories about a murder.
