Critical Disappearance

When a federal witness vanishes from an ICU without a trace, Dr. Mara Bennett knows something is wrong. The hospital says he was transferred. The records disagree. And the security footage—edited, overwritten—shows a stranger posing as family taking him away.

Mara should walk away. She’s a doctor, not a detective. But the patient had whispered about “unfinished business” and drawn a symbol on his wrist before he disappeared—a circle split by a cross. Now, that same mark keeps turning up in hospital files that should’ve been deleted.

With a nurse who won’t stop asking questions, a hacker who owes her a favor, and a detective who’s learned to trust her instincts more than his orders, Mara begins tracing the threads. Each one leads deeper—into a network of hidden ledgers, ghost wings, and “patients” who were never meant to wake up.
