"Álvarez's deep shades of blue and violet give the nocturnal forest a magical undertone while contrasting with the fireflies' fuzzy yellow lights and the white glow of the full moon. And her bug-eyed, bright teal fireflies are adorable, accessorized with cloche hats, newsboy caps, and leaf umbrellas." --Publishers Weekly
