Sometimes, you just can't say "I love you" enough—but this enthusiastic cow is sure gonna try. With the same infectious exuberance they displayed in Duck! Rabbit! and other picture books that grownups like as much as children do, Amy Krouse Rosenthal and Tom Lichtenheld pile on the cow puns in a moo-ving declaration of utter affection. Adorable cow cartoons—black and white, of course, with occasional touches of red—show our bovine valentine painting hearts, dancing, and leaping over the moo-n, all of which makes the message here both heartwarming and crystal clear.
