Lemonade Mouth is a young adult novel by Mark Peter Hughes, published in 2007 by Delacorte Press.

The novel was adapted into a television film by the same name starring Bridgit Mendler, Adam Hicks, Hayley Kiyoko, Naomi Scott, and Blake Michael and premiered on Disney Channel on April 15, 2011.

Five teenagers—Olivia, Stella, Charlie, Wendel "Wen", and Mohini "Mo"—meet after all ending up in detention for different reasons.

Before the Bash, the lemonade machine that inspired the band is taken away as part of an agreement with a sports drink company that is sponsoring the school's new gym.

At the Bash, many of the students are surprised at Lemonade Mouth's music when they take the stage because the band uses instruments like trumpets and ukuleles.

The bandmates develop friendships and bonds with each other when they arrive at Olivia's house to console her after her cat dies.

However, things go downhill when Stella's ukulele breaks, Wen injures his lip, Charlie burns his hand, Olivia loses her voice, and Mo gets sick.

Though the band does not do well in the competition due to their recent problems, their fans support them nevertheless, singing along to their songs to lift their spirits.

Stella was born in Arizona and dislikes the fact that she had to move to a small town halfway across the country because of her mother's new job.

Charlie, who has a sweet and shy nature, plays the drums, congas, bongos and timbales for the band.

The book received a positive review from Publishers Weekly, who called it "a rock-n-roll The Breakfast Club for the literary set", and "an enjoyable romp that touches on wide-ranging themes".
