Little, Brown, the publisher of L.C. Rosen's Jack of Hearts (and Other Parts) (2018), described Rosen's book as "Riverdale meets Love, Simon." Jack of Hearts follows the eponymous Jack, a young man who enjoys having sex. Despite the ostracization that he faces because of this, Jack carries on because he loves himself and is okay with his life. After all, it "could be worse" for him.
However, Jack's life takes a turn for the worse: he starts receiving odd, anonymous love letters, forcing him to stop writing his weekly sex advice column. As a result of these letters, which Jack starts to take to heart, Jack starts to change his behavior. He tones down his personality, has less sex, and is less boisterous. But the letters continue, inviting Jack to find the person sending him letters. He takes the letter writer on their invitation and begins to search for their true identity before things take an even darker turn for the worse.
Reviews for Jack of Hearts were mixed. Some called the book "graphic" and "perverted" and questioned why the book is being marketed to young adults. However, the novel also received glowing reviews from many professional review outlets, including Kirkus Reviews, which said that the book is "A sex-positive and thoughtful romp with humor and heart."
