The illustrator of Eve Bunting’s Tweak Tweak and Have You Seen My New Blue Socks? makes his Clarion debut as author/illustrator with a tender book about loneliness and friendship. Leo, a mailman, takes in a small bird, Cheep, who missed the autumn migration of his flock.When spring comes and Cheep moves on, Leo is sad to see him go, but he also has hope, and the letter he has been longing for finally arrives. Sergio Ruzzier’s signature, slightly surreal animal characters and the setting, rendered in brilliant colors, make this simple, eloquent story a visual treat for the very young.
