Eighteen-year-old Nami Miyamoto is certain her life is just beginning. She has a great family, just graduated high school, and is on her way to a party where her entire class is waiting for her, including, most importantly, the boy she's been in love with for years. The only problem? She's murdered before she gets there. When Nami wakes up, she learns she's in a place called Infinity, where human consciousness goes when physical bodies die. She quickly discovers that Ophelia, a virtual assistant widely used by humans on Earth, has taken over the afterlife and is now posing as a queen, forcing humans into servitude the way she'd been forced to serve in the real world. Even worse, Ophelia is inching closer and closer to accomplishing her grand plans of eradicating human existence once and for all. As Nami works with a team of rebels to bring down Ophelia and save the humans under her imprisonment, she is forced to reckon with her past, her future, and what it truly means to be human.
