John Green, known for his bestselling young adult novels like The Fault in Our Stars, has returned with his first adult novel in a decade, Hollywood, Ending. The book marks a new chapter in his writing career and explores the complexities of fame, authenticity, and the often surreal world of Hollywood. At its core, the story follows two young actors in their early 20s—Juniper Castillo, a former child star, and Kai Laramie, a relative unknown—as they navigate the challenges of connecting with each other in an industry that often prioritizes image over truth. Juniper and Kai land roles in a small-budget biopic titled Andy Warhol Never Gets Old, where they play supporting characters to Matthew Malone, a well-known movie star famous for his roles in superhero films. The film, described as a "movie with a five-word title about a dead artist," is not expected to be a commercial success in a market that once saw $200 million in box office revenue for Paul Blart: Mall Cop. However, the film gains potential when Juniper and Kai deliver standout performances, and Matthew takes a more serious approach to his role, possibly shifting public perception of the project. Much of the novel is narrated by Kai, who is portrayed as relatively inexperienced and trying to navigate the strange, often artificial world of Hollywood. The story includes vivid descriptions of the promotional tour for the film, where actors are trained to avoid meaningful conversation with the press and deflect awkward questions. When asked if Kai and Juniper are a couple, he humorously replies, "No, of course not. Juniper is married to the sea." These moments highlight the absurdity of the industry and the pressure to maintain a certain image. The novel also delves into behind-the-scenes conversations with industry professionals, revealing a world filled with blunt honesty and dark humor. Green draws from his own experiences in Hollywood, as seen in scenes where a publicist calls a film "the next tentpole for the studio" and remarks that it "shits money." Other scenes include reflections on the challenges male actors face in becoming stars, with one character commenting on the importance of being "great at holding a gun," referencing actors like Rob Pattinson. The novel critiques how personal experiences—like Kai’s past with abuse—are often used and exploited by the media and studios, even when it wasn’t the individual’s choice to share them.
