Meet Narwhal: Unicorn of the Sea! (Tundra, $12.99 HB/$7.99 PB) as he and new best bud Jelly deliver a promising start to a new series of graphic novels for beginning readers. While the happy-go-lucky-whale and the slightly cynical jellyfish each doubt that the other really exists—you’d probably think you were imagining things, too, if you’d never seen a narwhal before!— it’s not long before they develop a true and lasting friendship. Each mini-chapter in Ben Clanton’s adorably zany adventure is a story unto itself; book lovers young and old will especially appreciate the cleverness of the final tale, in which Narwhal shows Jelly that all you need to make a bunch of blank pages into the best book ever is a little bit of imagination. Ages 6-9.
