Vanished on Vacation — Jenifer Ruff

Three sorority sisters enjoy a long weekend at an exclusive resort, until one of them disappears.

On the last day of her vacation at the Azure Cove Resort in Mexico, Avery Jennings, a college senior from University of Virginia, tests positive for Covid and must quarantine. That's the last anyone hears from her.

FBI Agents Victoria Heslin and Dante Rivera accept an invitation from the Mexican Federales to assist with the missing person investigation. As the search commences, it appears everyone is hiding secrets, including Avery's family and friends and the luxury resort's staff and guests. It's up to Victoria to figure out which of those secrets might lead to Avery.

The mystery intensifies when another resort guest vanishes. Frustrated with the investigation, Victoria defies orders and takes matters into her own hands. Determined to bring the missing home, Victoria just might die trying to find them.
