Chick Lit is the literary equivalent of the Chick Flick, referring to books written explicitly for an adult female readership, and meant to appeal to their (presumed) tastes. Rather than referring to books by women or about women in general, it has contracted to represent a specific genre. The heroines are usually young, attractive professional women, and the book will often focus heavily on their relationships, careers, sexuality, shopping tastes and habits, fashion, and so on. The tone is usually light and humorous, possibly self-effacing.
