For readers who also suspect their siblings are aliens from another planet: Meet Alex, the narrator of this book of evidence against his brother's being human. The facts: As a baby, William babbled; he is from a family of short people but is tall; he never mastered the human art of sleeping calmly in a bed. Alex presents his evidence to his parents, who give him the brush; not until Alex is about to depart for college do the brothers confront each other, when it turns out that William has been nursing his own suspicions about Alex. The concluding illustration shows William with antennae and a cerulean complexion. The text, in a typeface that approximates hand-lettering, flows comfortably into the goofy, friendly illustrations, which convey the playful sentiments of the story. It may inspire similar investigations in many households. (Picture book. 5-9)
