In sixth grade now, the wildly imaginative Rex Zero and his friends hatch a plan to replace Miss Garr, the substitute teacher from hell, and Rex takes on the persona of none other than "Dr. Love." Of course, events spin hilariously out of control. Miss Garr's cruel behavior is a mystery to Rex. But then, Rex's world is full of mysteries! There's the beautiful woman in white. Why does she have a black eye? There's the little black book filled with names. Who could it belong to? And why has Rex's father hidden a letter that "Mein Liebchen"? Could all these things have something to do with the mystery of love? Underneath all of this is the age-old question of how to stand up and be a man. For if, as Rex's dad says, "a man's got to do what a man's got to do," how does Rex know what to do and when to do it? Delightfully eccentric characters, humorous scenes of well-intended plans gone awry, a finely crafted plot interwoven with serious themes about love and war―this new Rex Zero is a gem! Rex Zero, King of Nothing is a 2009 Bank Street - Best Children's Book of the Year.
