Carl the protective Rottweiler and Madeleine the charming toddler return for another playful adventure in this popular series. The very brief text explains that the family is arriving at their lakeside cabin to prepare for a picnic dinner and to take in a fireworks display with friends. Madeleine and Carl should settle down for a nap, but they take off on another independent escapade, away from any watchful parents. The daring duo begin by canoeing together on the lake, an activity that may give safety-conscious parents pause, especially when the canoe tips over. (Responsible Carl made sure Madeleine was wearing her life jacket and even tightened the strap for her.) They move on to a full afternoon of play at the park and beach, returning home in time for dinner but too tired to stay awake for the fireworks. Day’s paintings are as charming as ever, particularly in the joyful scenes of Madeleine riding on Carl’s back, but one must wonder when Carl will be ready to retire. (Picture book. 3-5)
