John Green, the bestselling author of popular Young Adult novels like The Fault in Our Stars, has released his first adult fiction book, Hollywood, Ending, after nearly a decade of writing for younger audiences. The novel follows two young actors navigating the pressures of fame, their developing romance, and the challenges of working on a biopic about artist Andy Warhol. Green has been careful not to reveal plot details in interviews or on social media, encouraging readers to experience the story without prior knowledge. The book explores themes that Green has been thinking about for years, particularly how Hollywood turns personal experiences into public entertainment. He noted that writing for adults was not much different from writing for teenagers, as both groups are "intellectually sophisticated and careful readers." The story delves into the struggles of early adulthood, including the search for identity, meaningful relationships, and purpose in life. Green often writes in a shed on his property in Indianapolis, where he listens to the music of The Mountain Goats and uses a Moccamaster coffee maker with Keats & Co. coffee, a brand he co-founded with his brother, Hank Green. The company donates all its profits to charity and collaborates with small farming communities and top roasters to create high-quality coffee. Green is currently embarking on a 20-city book tour, traveling with only a carry-on suitcase filled with essentials, including a book. His favorite book of the year is Canon: A Novel by Paige Lewis, for which he wrote a blurb. He organizes his personal library by genre, separating works by deceased and living authors, following advice from the New York Public Library's Guide to Organizing a Home Library. Before the tour, he spent time making hot sauce with his mother using peppers from their shared garden, sharing the process on social media and YouTube, though he keeps the family recipe private.
