This is a science like book about an explorer who goes to Antarctica to watch the Adele penguins. My 3 year old loves it, probably because the author does not condescend to him by using foolish words. For instance, after the two penguins build their stone nest "Now the male penguin gets on the nest to keep the eggs warm. A penguin has a place on its body with no feathers. It is called an incubation patch. This patch is warm. It keeps the eggs warm." So my son learns sophisticated ideas easily. I am trying to find other great science books like this, but it is a real bear - especially since most are full of political correctness instead of science! By the way -62 pages.
