In a quiet, introspective novel, Debbie, 13, faces one of the worst things that can happen to the young; she’s lost a best friend, Maureen, to a boring, rather unpleasant classmate, Glenna. With carefully observed details and moments, picture-book creator Perkins (Clouds for Dinner, 1997, etc.) shows why Debbie can believe that she’ll never have a happy day again. Of course, there are others around, such as her new neighbor, the worldly Maria, and girls from school, but none of them is as wonderful as Maureen. Debbie finds herself hating Glenna, but a kindly teacher helps her realize that Glenna didn’t “take” Maureen—Maureen left. It all adds up to a just examination of one of the small but piercing sorrows of growing up, with a cast of arresting characters, freckles of humor, and black-and-white drawings that enhance the muted tale; Perkins gives the significance of friendship its due, and then some. (Fiction. 10-12)
