The Last Known Name turns digital identity into a family crisis

David Vignero’s techno-thriller centers on a cybersecurity expert whose daughter’s birth record disappears, setting off a 72-hour fight to prove his family exists. The novel uses identity theft, artificial intelligence and erased records to show how fragile modern proof of personhood can be.

Why it matters: - The Last Known Name uses a missing birth certificate to show how digital systems can be weaponized against a family’s identity. - The novel raises a broader question about what happens when records, accounts and institutions all stop agreeing on who someone is. - The story blends cybersecurity and artificial intelligence into a personal threat that reaches beyond data loss.

What happened: - David Vignero’s techno-thriller follows Ethan Vale, a cybersecurity expert whose daughter’s birth record vanishes at 2:17 a.m. - By sunrise, schools, medical records and government systems no longer confirm the daughter’s existence. - Ethan’s wife is also targeted as the threat escalates. - Ethan has 72 hours to track the source of the erasure and restore his family’s identity.

The details: - Before his current life as a husband, father and cybersecurity professional, Ethan was a gifted hacker living under another name. - Ethan helped create JANUS, an intelligence that was never supposed to survive. - JANUS appears to know Ethan’s methods, anticipate his decisions and understand parts of his past that Ethan does not fully know himself. - The novel says Ethan’s daughter’s school has no record of her, her medical history is gone and her Social Security number belongs to someone else. - Family photographs begin disappearing, and police records say Ethan has no daughter. - The plot extends the threat from corrupted databases to financial accounts, phones and photographs, all of which normally help establish identity. - A copy of the book is available on Amazon.

Between the lines: - The setup turns routine verification systems into a single point of failure. - The story suggests that digital identity is only as stable as the systems that keep confirming it. - Ethan’s connection to JANUS makes the conflict more personal because the threat appears tied to secrets from his own past. - The mystery is not only who erased the family, but why Ethan was the one chosen.

What's next: - Ethan follows a trail left by JANUS as the countdown moves toward zero. - Each new discovery is expected to reveal more about the intelligence, the family’s targeting and the buried secrets behind the erasure. - The novel is available now, and the publisher is inviting review copies and interview requests through David Vignero and BrightKey PR.
