New adult (NA) fiction is a developing genre of fiction with protagonists in the 18–29 age bracket.[1][failed verification]St. Martin's Press first coined the term in 2009, when they held a special call for "fiction similar to young adult fiction (YA) that can be published and marketed as adult—a sort of an 'older YA' or 'new adult'".[2] New adult fiction tends to focus on issues such as leaving home, developing sexuality, and negotiating education and career choices.[3] The genre has gained popularity rapidly over the last few years, particularly through books by self-published bestselling authors such as Jennifer L. Armentrout, Cora Carmack, Colleen Hoover, Anna Todd, and Jamie McGuire.[4][5]
The genre originally faced criticism, as some viewed it as a marketing scheme,[6] while others claimed the readership was not there to publish the material.[7] In contrast, others claimed the term was necessary; a publicist for HarperCollins described it as "a convenient label because it allows parents and bookstores and interested readers to know what is inside".[8]
