Description: Meet Truffle in three linked stories: In “Truffle the Rockstar,” Truffle wants to form a band with his best friends Flo and Riad. In “Truffle Loves Nina,” Truffle asks his parents, his friend Riad, his big brother, Louis, and the man who works at the library, for advice on how to let his heart do the talking. And in “Truffle Tackles Existence,” Truffle attends his great-grandmother’s funeral, which gets him thinking about the world around him. Fans of Louis Undercover will be delighted that Truffle — Louis’s funny, music-loving little brother — now has his own book!
