Diana O'Toole's life is going perfectly to plan. At twenty-nine, she's up for promotion to her dream job as an art specialist at Sotheby's and she's about to fly to the Galápagos where she's convinced her surgeon boyfriend, Finn, is going to propose.

Once she's in the Galápagos, the world shuts down around her, leaving Diana stranded - albeit in paradise. Completely isolated, with only intermittent news from the outside world, Diana finds herself examining everything that has brought her to this point and wondering if there's a better way to live.

But not everything is as it seems . . .
