In the wake of The New Yorker’s recent “20 Under 40” list of gifted fiction writers who have not yet reached age 40, the literary community has turned its attention to even younger emerging talent. Here is that next generation:

Rachel Besculides’s second collection of letters to Justin Bieber, “No One Loves You Like I Do,” was published in January.

Emma Bryant’s biography of Jennifer Costawicz, “Jennifer Costawicz Is Mean and Fat and Is Not My Friend Anymore,” is available in paperback.

Matthew Chu’s anthology of essays, “Big Dogs Are Scary. And Dragons,” was published in March. He lives in Michigan.

Joseph DiPasquale, author of the collection of light verse “My Dad Is Stronger Than Your Dad,” is working on his first novel.
