Forensic accountant Ilyra Venn expects a routine estate audit. Instead, she finds a dead man's handwritten ledger tracking fifteen years of disappearances — with one entry dated three days after his own death. The deeper she digs, the faster the ground disappears: accounts vanish, records erase themselves, and her own name turns up inside the very network she's investigating. With a skeptical county investigator as her only ally, Ilyra has seventy-two hours to expose the system before it erases her too.
