"Adult books for YA readers are my jam. I love when I settle in with a good book marketed for adults and find the themes that I love in YA: coming of age, with a voice that is reminiscent of that YA books feature, and characters who are in their teens or (very early) twenties. Think older titles like Curtis Sittenfeld's Prep or Megan McCafferty's Sloppy Firsts, both of which would likely be published as YA or marketed heavily toward YA readers in today's book world. These adult books for YA readers are often called crossover books, and they're frequently among the most requested by those who ask me for book recommendations, too.
I've pulled together a list of great crossover books published in the last handful of years. Your favorite might not be on the list; neither may be the title published five or ten years ago. This is meant to be a wide-ranging list of mostly non-genre reads, including contemporary titles and nonfiction." Kelly Jensen/Book Riot
