Federico doesn’t mind being a political hostage of the Pope, especially now that he has a cat as a friend. But he must admit, a kitten walking into a wardrobe and returning full-grown a moment later is quite odd. Even stranger is the man named Herbert who emerges from the wardrobe the next night, an art collector from the future. Herbert barters with Federico to get a sketch signed by the famous painter Raphael, but his plans take a turn when he hurries back to his era, desperate to save a dying girl. Bee never wanted to move to New Jersey. When an elderly neighbor shows Bee a sketch that perfectly resembles her, Bee, freaked out, solidifies her resolve to keep to herself. But then she meets the cat and discovers a mysterious cabinet in the attic that leads her to Renaissance Rome. This epic, original, and compelling time-slip adventure by Newbery Honor author Catherine Gilbert Murdock is full of action, mystery, history, art, and friendship. Features black-and-white art of Da Vinci’s cat by Caldecott Medalist Paul O. Zelinsky throughout.
