4/5 ⭐ Sarah Pearse is back with another destination mystery featuring Detective Elin Warner. A family trip to an all-new eco-retreat to help reconnect and learn more about new family members starts off as they travel to the island clouded with a dark past. The cast of characters presented covers the gambit, self-absorbed influence who scored the tickets, freeloading boyfriends, distant sisters, and cousins with a tragic past. Take your pick there is one of each. And they are all stranded together on this island with a murderer picking them off one by one. We definitely get to see some character growth with Elin which I loved. Instead of being stagnant and making it a focus of her character we get to see her grow from the traumas of her past. As well as see how she does solving a crime in an official capacity and being backed by her department. I love a locked room mystery and boy, does Pearse know how to structure one. The twists in this were flawless and kept me on my toes....
