Less is a satirical comedy novel by American author Andrew Sean Greer, following gay author Arthur Less as he travels the world on a literary tour. The book covers themes such as romantic love, LGBT relationships, age, and travel. Greer began writing Less as a "very serious novel" but found that "the only way to write about [being gay and aging] is to make it a funny story. And I found that by making fun of myself, I could actually get closer to real emotion – closer to what I wanted in my more serious books."
