Saving Each Other by Capri Posey

Maria is an inexperienced vocational nurse desperate to get out of Los Angeles. When she uploads her résumé to an employment site, she never dreams it could lead to being considered by the famous jet-setting Mitchell family who live on a remote tropical island.

Brian is a rescue pilot who wants to settle down, but is far too busy to play the dating game. He never dreamed that Grandma's nurse might turn out to be everything he ever wanted, delivered right to his doorstep.

Neither are aware that they are being stalked and targeted by a deranged serial killer, bent on destroying all that they hold dear.

[This is a sweet / clean / wholesome romance with a BBW / curvy protagonist. It's also a family saga with a thriller subplot. Language includes one instance each of "damn" and "hell", both uttered under extreme duress. There are some scary/tense/violent parts related to the thriller aspect. Lots of delicious food and cooking in the plot, so maybe not best to read if you're hungry!]
