Full disclosure, I haven’t read this one, but the plot sounds like the lovechild of The Bachelorette and Survivor, so it seems worth a look! It follows Orie Lennox, who is cast on a rugged reality game show, where she’ll be stranded on an island with a group of strangers, all in hopes of strategizing her way into winning a million dollars. But when she touches down on a beach in the South Pacific, she realizes she’s been cast on an experimental and romantic edition of the show, which basically combines surviving the elements with speed dating. Oh and her high school crush, Remy, has been cast, too, making things even more interesting.
