The book was first published in September 1993 by Scholastic, and reissued in 2003^[4] and on September 1, 2008.^[5] An audiobook, narrated by Jorjeana Marie, was published in 2015 by Scholastic Audio.^[6]

Carly Beth Caldwell is a naive, timid and gullible 11-year-old girl who scares easily. Thus, she is constantly ridiculed by Steve Boswell and Chuck Greene at Walnut Avenue Middle School. The pair play several tricks on her, such as offering a sandwich containing a live worm. After school, she goes home and finds her mother has made her a plaster of Carly Beth's face as a symbol of love. When she goes to her room, her younger brother Noah scares her in a duck costume also made by their mother. At the school science fair, Steve causes a panic by announcing his pet tarantula has escaped, and exploits Carly Beth's arachnophobia by pinching her leg, leading her to believe that the tarantula has bitten her. She flies into a frenzied and destructive panic and is once again humiliated in front of her teachers and classmates. Carly Beth exasperatedly vents to her friend Sabrina and promises vengeance upon Steve and Chuck. She plots to go to a new shop that has opened, which sells frightening costumes, and plans to scare Steve and Chuck as payback.

Within the shop, Carly Beth sneaks into a back room and discovers a row of hideously deformed masks. The store owner reluctantly sells her one of the masks and Carly Beth goes home in delight. After successfully scaring Noah with the mask, she dons it again on Halloween evening and manages to scare Chuck and Steve. However, as the night goes on, her voice deepens and her behavior becomes violent; she strangles Sabrina and frightens children she does not know. Carly Beth later discovers that she is unable to remove the mask and realizes to her horror that the mask has become one with her skin.

Carly Beth returns to the shop, where the shopkeeper tells her that the "masks" in the back room are actually living faces that can only be removed by a "symbol of love", but if it attaches itself to her or another person again, the fusion will be permanent. The other masks suddenly come to life and begin to pursue Carly Beth. While running away from the masks, she realizes that the plaster mold her mother made is a symbol of love. Carly Beth finds the mold and uses it to deter the masks and remove the mask from her face. She returns home to her mother, tossing the mask away. Noah later bursts in and asks her, "How do I look in your mask?"
