Glass houses / Madeline Ashby.

"Join a stranded start-up team led by a terrifyingly realistic charismatic billionaire, a deserted tropical island, and a mysterious AI-driven mansion--as the remaining members disappear one by one. A group of employees and their CEO, celebrating the sale of their remarkable emotion-mapping-AI-algorithm, crash onto a not-quite-deserted tropical island. Luckily, those who survived have found a beautiful, fully-stocked private palace, with all the latest technological updates (though one without connection to the outside world). The house, however, has more secrets than anyone might have guessed, and a much darker reason for having been built and left behind. Kristen, the hyper-competent "chief emotional manager" (i.e., the eccentric boyish billionaire-CEO Sumter's idea of an HR department) is trying to keep her colleagues stable throughout this new challenge, but staying sane seems to be as much of a challenge as staying alive. Being a woman in technology has always meant having to be smarter than anyone expects....and Kristen's survival skills are more impressive than anyone knows"-- Provided by publisher.
