Don’t Fear The Reaper by Michelle Muto
Haunted by memories of her murdered twin, Keely Morrison is convinced suicide is her only ticket to eternal peace. But in death, she discovers the afterlife is nothing like she expected. Instead of peaceful oblivion or a joyful reunion with her sister, Keely is trapped in a netherworld on Earth with only a bounty-hunting reaper and a sarcastic demon to show her the ropes.
When the demon offers Keely her ultimate temptation–revenge on her sister’s killer–she must determine who she can trust. Because, as Keely soon learns, the reaper and demon have been keeping secrets and she fears the worst is true–that her every decision changes how, and with whom, she spends eternity.
