“The simplified forms, curving lines, and muted colors in the watercolor illustrations suit this gentle, rather melancholy story well. . . . An engaging picture book with craft-project potential.” —Booklist
“Who is the ‘Best Friend in the Whole World’? After reading this sweet, sensitive tale, children can decide for themselves.” —The New York Times
“Salsbury never allows the tale to become maudlin or cloying, as Roland selflessly deals with disappointment, remaining a kind and compassionate friend. Watercolor illustrations, appearing as vignettes and both single- and double-page spreads, enhance the tale with lively, detailed depictions of Roland’s woodsy home, his expressions of sadness and joy, the sweet-natured Lucy, and, of course, the incredible Milton/Popkin. Young readers will sympathize with Roland and strive to emulate his kindness to his friends, whether real or imaginary. Life lessons gently told. Lovely.” —Kirkus Reviews
“This picture book is charming in its simplicity and thoughtful in centering empathy as it quietly affirms the specialness of imaginary friends.” —School Library Journal
