Neon Debt Protocol

Leia Morn wakes inside a corpse-processing capsule with a blade at her throat—and a voice in her head demanding her first promise. She was declared dead, her brother has been sold to an underground lab, and every broken vow will erase a piece of her memory. To save Nolan, Leia must use the Covenant Engine, trading fulfilled promises for impossible speed, heightened senses, and deadly strength. Her only way through the surveillance district is Kane Roe, a ruthless black-market escort who was supposed to be her enemy—but whose touch ignites a dangerous pull neither of them can afford. Then the engine shows Leia signing her brother’s transfer papers, while Kane secretly reports that the city’s missing heiress has finally awakened. If Leia trusts Kane, she may discover who she truly is; if she breaks the next promise, she may lose the last memory of the brother she’s fighting to save. Which will she sacrifice first—her freedom, her identity, or her life?
