Levithan started writing a “valentine” story every year for his friends, starting in high school. Collected here, they range from amusing, to embarrassing, to tender. Many of them feature gay characters, but not all of them. Included are brief stories about how his grandparents met (thus the title). These will appeal to teens who like to read romance. Reading the stories in measured portions will give a more satisfactory experience.
