Elephants march with the herd, polar bear cubs curl up safe in their cave, and otters drift on the ocean holding on to each other. Page by page, the peek-through hole gives a child a keyhole into the next animal family, and the reveal never stops being satisfying.

This is the newest entry in the bestselling series that began with Tree, and Britta Teckentrup's layered collage scenes are at their warmest here, because the subject is the one every small child cares about most: parents and their babies, staying close. It reads as a bedtime book and works as a first nature book, with real animal families from all over the globe.

The publisher suggests it for Mother's Day and Father's Day, and they are right, but it earns its shelf spot the other 363 days too: every die-cut keyhole turns the page into a small game of guess-who, and the answer is always the same — your family has you.
