"Milly and big sister Becca are members of the Midnight Club. And tonight is Milly's first outing! At exactly midnight, Milly wakes her sister. With Becca leading the way, they tiptoe along the shadowy hall and down the creaky stairs. There's so much adventure to be had in the middle of the night! They sit in Dad's big chair, dip into his jar of jellybeans, try on Mom's coat. One moment they're frightened by a shadow that looks like a monster, and the next, they're making shadow play of their own. A scratch at the back door has Milly's heart going boom bump boom, but it's just the president of the Midnight Club, their cat Oliver, who leads the way to more shenanigans. Eventually her big sister gets tired(!) but before they head back upstairs, Milly remembers the most important rule--The Midnight Club has to be a secret--and they put back dad's jar of jellybeans and hang up mom's coat. Then Milly, now comfortable in the midnight house and feeling bolder, leads the way back to their room, satisfied with her adventure, and with the secret of the Midnight Club safe inside her. ...
