When they were teenagers, Mia’s beloved cousin was murdered during their stay at an infamous castle in the Austrian Alps. As the only witness, Mia’s testimony put the killer behind bars, but it tore her life apart: the media accused her aunt, a controversial true crime author, of being involved. Now, a decade later, the murderer is appealing his conviction, and a popular true crime podcast starts covering the case, determined to exonerate him, and resurfacing lies about Mia’s family in the process.

Desperate to protect her aunt—and what she knows to be the truth—Mia returns to Austria. The castle is being revamped as a luxury hotel, and Mia gets a job as a nanny for the new owner, hiding in plain sight as she investigates, needing to set the story straight once and for all. But after someone mysteriously disappears on the property and sinister new evidence emerges regarding her cousin’s death, she realizes she might have accused the wrong man…and put her own life in danger.
