Riley's little sister, Megan, is confused by all the activity in their home as the holidays approach. Riley teaches her about all the wonderful things that come with Christmas: hot cocoa, decorating the tree, hanging stockings, baking cookies, and more. Megan's excited about all of these things, especially when her brother tells her about presents. But it's the lesson of celebrating family togetherness, and the birth of baby Jesus, that make the holiday—and this book—a heartwarming Christmas classic.
