I don't know the author but the premise sounds quite interesting:
Even being dead isn’t enough to get you out of maths class.
Dying wasn't on sixteen-year-old Riley Richardson's to-do list. And now, not only is she dead, but she's stuck in a perpetual high school nightmare. Worse still, she's stuck there with the geekiest, most annoying boy in the history of the world, ever.
In a school where the geeks are popular and just about everything is wrong, Riley has become an outcast. She begins a desperate quest to get back home, but her once-perfect life starts to unravel into something not nearly as great as she thought it was. And maybe death isn’t really that bad after all...
Welcome to Afterlife Academy, where horns are the norm, the microwave is more intelligent than the teachers, and the pumpkins have a taste for blood.
