Used book – Free Fall, Carol Higgins Clark

Las Vegas! The city of all possibilities and illusions... It's there that Regan Reilly, the charming detective, arrives, summoned by Danny, a childhood friend.

Danny produces a very "trendy" reality TV show, where couples on the verge of breaking up have a week to reconcile and rediscover each other - the most convincing ones win a nice sum of money. But here's the thing: Parker Roscoe, the channel's president, seems to be playing an ambiguous game, and Danny's work is poisoned by rumors, incidents, and the appearance of fake couples...

Who is trying to sabotage the show? Who is manipulating whom? As sharp as she is, Regan will have a hard time untangling this imbroglio where reality and spectacle intertwine, before an even more unimaginable denouement...
