Ollie & Moon (Random House, 2011) by Diane Kredensor and Sandra Kress, is a beautifully done picture book that seamlessly combines cartoon-style illustrations with real photographs. (I love the vivid photos! The cover is eye-catching.) The story follows best friends, Ollie and Moon, as they explore the city of Paris while playing a guessing game along the way. Young readers will enjoy exploring and playing right along with them. See if you can guess the surprise that Ollie has for Moon at the end of the book. No peeking!
