Another assembly of mind-expanding images from a gifted photographer who now has at least 24 fine concept books for children to her credit. Here, 14 pairs of color photos explore the concepts suggested in the title--mirror-like reflections in still surfaces like windows or puddles; distorted images in a huge, dented horn or reflective glasses. Hoban contrasts colors, textures, and ideas: the masts of anchored sailboats and the spires of a chateau, each transformed by rippled water; the shadow of a thing unseen (hands making a cat's cradle) or a shadow that accentuates the thing seen (tall grass on a beach). The last, single photo is a fascinating self-portrait of Hoban taking her own picture in a many-faceted mirror. To enjoy simply for its beauty, to ponder for its subtle meanings, or to discuss for its extraordinary variety--a splendid book with multiple pleasures and uses. Although the subjects will appeal to young children, there's nothing here to limit its appeal to them.
