That's a Wrap by JD Davis

 Actor Daxton Knight is a rising star and appears to be have everything, including fame, fortune, and his pick of gorgeous women, but appearances can be deceiving as he begins to receive some distasteful hate mail. It seems someone holds a grudge against the superstar, and when Dax relocates to film his next movie, he is assigned a temporary personal assistant. Sonny Winslow is an aspiring writer looking to get her book published, but she needs to make some money in the meantime. She and Dax get off to a rather rough start when his model girlfriend takes an instant dislike to the author, and Dax insinuates Sonny is using his fame to help her career. But when Sonny starts receiving the same threatening messages, she and Dax join forces to figure out who their stalker could be. To their dismay, the danger mounts with each encounter from their unknown predator, and they must watch each other’s back while still working together on the film. Each scene intensifies, and you aren’t sure how it will end until the director yells, “That's a Wrap.”
