Telling my grandmother that I was going to be a Horn Book intern was comparable to what it would have been like telling other ­relatives that I was going to be working for the New England Patriots. Yaya (known to all but her grandchildren as Natalie Coleman) has her own standards for determining the quality of children’s books, and a strong sign for her was an endorsement from The Horn Book Magazine, which she’d first encountered during a children’s literature class at Cal State–Los ­Angeles in the 1960s, when the magazine hadn’t even reached its semicentennial anniversary.
