Resort at Castaway Bay: Hide and Seek

Sydney Whitmore, a forensic psychologist working for the FBI, moves to Shipwreck Island and renews her relationship with Ezra Reinhold, a reclusive billionaire who enjoys poking around in cold cases and has the means to hire the best people to find the answers no one else has been able to.

In book 6 in the series, Syd is asked by the FBI to escort the child of a key witness in a murder trial to a safe house after the US Marshall who'd been watching the child was killed. The Marshall who'd been watching the child managed to get off a message before she died letting the FBI know that there was a mole within the organization who'd given up their position, so Syd and the child set off on a journey where no one can be trusted and nowhere really feels safe.

Meanwhile it's Christmas on Shipwreck Island and the entire family is involved in seasonal events and activities.
