An easy-to-read book which tells that bones give shape to the body, grow, protect important organs, need calcium, are connected at joints by ligaments, grow together when broken, and are not scary. The softness of cartilage is demonstrated in a first-person account of a boy's pressing his nose against a bakery window to look at some cookies, and the presence of marrow in the center of some bones is worked into a trip to the butcher shop with mother. The illustrations of these and other scenes, designed to amuse and pleasant to look at, do little to reinforce the instruction. Elementary concepts are presented here on a younger level than in other bone books, but less information is conveyed -- with more anecdotes and less pertinent pictures -- than in, for example, the Showers books on blood, babies and the heart in the same series.
