Epistolary novel An epistolary novel is a novel written as a series of documents. The usual form is letters, although diary entries, newspaper clippings and other documents are sometimes used. Recently, electronic "documents" such as recordings and radio, blogs, and e-mails have also come into use. The word "epistolary" is derived from Latin from the Greek word ἐπιστολή "epistolē", meaning a letter (see epistle).
New adult fiction New adult (NA) fiction, also rendered as new-adult fiction, is a developing genre of fiction with protagonists in the 18–30 age bracket. St. Martin's Press first coined the term in 2009, when they held a special call for "...fiction similar to YA that can be published and marketed as adult—a sort of an 'older YA' or 'new adult'". New adult fiction tends to focus on issues such as leaving home, developing sexuality, and negotiating education and career choices. The genre has gained popularity rapidly over the last few years, particularly through books by self-published bestselling authors like Jennifer L. Armentrout, Cora Carmack, Colleen Hoover, and Jamie McGuire.
