The End of Iris

Iris has the perfect life from the outside, but a long line of family history of depression holds her hostage. She wakes up on her twenty-fourth birthday with plans to end her life. After her death, she wakes in what she finds to be called the In-Between, which turns out to be more like a personal hell.
Iris must watch as her family grieves and comes to realize that the pain she'd suffered on earth didn't leave when she died, it just clung to all who knew her.
Does she find peace? Or does she grieve the life she once had?
