New baby sisters, substitute teachers, and friends (even if it’s a bowling ball) are frequent themes in short novels for young readers. Favorite authors such as Karen English and Andrea Cheng deliver new titles in popular series, while Neil Gaiman and Mal Peet (who usually write for older readers) provide humor and thought-provoking storytelling for kids who are getting comfortable reading on their own. The following titles selected by the editors of Junior Library Guild are just the ticket.
