Wonder is a children's novel by Raquel Jaramillo, under the pen name of R. J. Palacio, published on February 14, 2012.
Palacio wrote Wonder after an incident where she and her three-year-old son were waiting in line to buy ice cream. Her son noticed a girl with facial birth defects. Fearing he would react badly, Palacio attempted to remove her son from the situation so as not to upset the girl or her family but ended up worsening the situation. Natalie Merchant's song "Wonder" made her realize that the incident could teach society a valuable lesson. Palacio was inspired by Merchant's lyrics and she began writing. The book has a released spin-off, 365 Days of Wonder: Mr. Browne's Book of Precepts. In August 2015, the book Auggie and Me was published. A film adaptation is set for release in 2017.
