Alec Greven

Leave it to a fourth-grader to make one of life's complexities look like child's play. With How to Talk to Girls, 9-year-old Alex Greven lays out some elementary principles: comb your hair, dress nicely, try not to act desperate, and don't overdo it with the compliments. With accompanying illustrations, Greven's book makes for some whimsical—and remarkably practical—advice on an age-old dilemma.
