She woke up three years in the past with no memories — only a System whispering that she was murdered. On the morning of her engagement party, 23-year-old heiress Elena Cross wakes to a stranger's voice in her head: "YOU WERE MURDERED." She remembers nothing of the future. But the NEMESIS SYSTEM remembers everything — and it sells the truth one mission at a time. A flash of rain. A terrace. A hand on her back. Someone she loved killed her for the Cross Group fortune, and the System will name them... for a price. To earn the truth, Elena must obey the voice: break her engagement, ruin her fiance, and smile at the friends who may have buried her. Every mission buys another fragment of her own murder. But the deeper she digs, the more the System takes from her. And the one man she cannot scan — the ruthless Adrian Wolfe — may be the only one she can trust.
