The protagonist is a teenager named Alton Richards. Alton's rich great-uncle, Lester Trapp, plays duplicate bridge but has lost his sight due to diabetes. In this story, Alton receives a phone call from his uncle who wants him to be his "cardturner", serving as his eyes and hands. Even though Alton initially knows nothing about bridge, he and his uncle are usually successful. As the story goes on, Alton develops a relationship with his uncle that he feels that he created himself, rather than his mother telling him to 'love' his Uncle.

Frank Cottrell Boyce of The Guardian writes that "The book feels like one long, deadpan dare, as though Sachar has made a bet with himself that he can make the most boring setting thrilling." and praises "The genius of Sachar's prose is that it's so plain and unshowy you don't notice the daredevil artistry of his storytelling until it's too late.". The New York Times suggests that The Cardturner "might be young adult literature’s first novel best read with an experienced partner and a full deck.". The book was also reviewed in the Bulletin of the Center for Children's Books.
