Every Day is a young adult romance and fantasy novel written by American author David Levithan.

Additional characters include Kelsea, Austin, Hugo, Vic, George, James, Nick, Jolene, and Jacob.

"[1] Susan Carpenter of the Los Angeles Times wrote, "It's the rare book that challenges gender presumptions in a way that's as entertaining as it is unexpected and, perhaps most important, that's relatable to teens who may not think they need sensitivity training when it comes to sexual orientation and the nature of true love.

"[6] Frank Bruni of The New York Times had this to say of Every Day, "It demonstrates Levithan's talent for empathy, which is paired in the best parts of the book with a persuasive optimism about the odds for happiness and for true love.

"[7] Chelsey Philpot of The Boston Globe remarked, "The ending is abrupt and leaves you wishing for more explanations...But maybe it only feels that way because we're not ready to let A go.

'"[8] In June 2017, it was announced that Every Day would be adapted into a feature film, with Angourie Rice starring as Rhiannon.

Jesse Andrews, author of Me and Earl and the Dying Girl, wrote the script while Michael Sucsy directed.
