Hoping for Hemingway by Kelsey Kingsley

Clara McKinley has high standards.
Cursed with a love for the classics, she finds herself often disappointed with the modern world—men included. So, it is no surprise that, at forty-two, she finds herself single and losing hope for her love life.
Until she meets author August Gordon, an attractive—and younger—man with the same passion for all things vintage and equally picky taste. With him in her life, it isn’t long before Clara begins to believe she’s finally met her match.
But when August’s fight with mental illness becomes too much for him to bear, Clara starts to wonder if she possesses the strength—and hope—to help him win the battle.
