In The Riddle of the Robin by Valerie Tripp, the WellieWishers are so excited to celebrate spring, but especially when they discover that a robin has moved into their garden. The girls visit the robin every day, but one day after a storm, the robin is gone. The girls search high and low in the garden, but cannot seem to locate their robin. Has their favorite bird left the garden for good? Includes a section in the back for parents to help encourage children to learn more about birds in a hands-on way. Recommended for ages 5 years and older.
