Two years ago, Jayde Holloway discovered she had the power to erase memories by accidentally wiping the memories of her best friend Jenny at the end of their senior year. Now, shut off from the world, Jayde exists solely for her role as the Sin Eater, an entity who can take away a person's every bad memory if they wish... for a hefty price. Under her new strict boss Jak, who consistently keeps her under his watchful eye through blackmail and constant reminders of all her mistakes, Jayde is lonely. Travelling back to her hometown of Palmsville, Jayde secretly meets Aiden and Amber, siblings who have a haunted past of their own. The three new friends bond as they take a tour of the town Jayde knows so well, sparking the woeful feelings and regrets she has tried so hard to ignore. When her painful memories begin to overwhelm, Jayde must make a choice: remain chained to a familiar but hurtful past or reveal all her darkest secrets for what could be a better future. Sin Eater is a story about the power of memories, good and bad, with a focus on the importance of friendship.
