In the sequel to "All the Worlds Between Us," swimmer Quinn Hughes has given up a lot in order to be an Olympian: her social life, her love life, and everything that comes with being a normal twenty-three-year-old. Just days away from competing in the Tokyo Games, Quinn runs into her childhood best friend and high school sweetheart, Kennedy Reed. Five years earlier, they’d made a pact that they would try again if their paths ever crossed, and now she can’t shake the feeling that this is a sign. But Kennedy has a whole life in New York City, and Quinn’s at the opposite end of the country in San Francisco, struggling to redefine who she’ll be after the Olympics. Feeling lonely and lost from everything she’s given up, Quinn finds comfort in reconnecting with Kennedy, and they both discover that time and distance have only fueled their passion. As Quinn comes to terms with herself and what the future holds, she’s sure of only one thing: she’s not letting the only girl she’s ever loved get away for the third time.
