Amazon Prime Video. Less than a week before the series launched on June 17, the coming-of-age, young-adult drama -- adapted from author Jenny Han's best-selling novels -- earned an early pickup for season 2, guaranteeing more romance, heartbreak and growing pains for the main heroine, Belly Conklin. The seven-episode freshman season, which largely follows the first book in Han's trilogy, centers around Isabel «Belly» Conklin as she, her mother Laurel and her brother Steven spend their annual summer vacation at the beach house of her mom's best friend, Susannah.
