When snowflakes fall, two sisters react very differently. One is excited and the other is wary. The first sister spends the morning outdoors, playing until she's all tuckered out. Meanwhile, the second sister stays indoors, becoming ever more curious about the drifts outside. Soon, they switch places, and spend the second half of the day retracing each other's footsteps. But each sister puts her own unique spin on activities like sledding, baking and building. The simple mirrored text is spare and lovely, and each spread is split to show what each sister is doing independently--until at last they come together in the sweet, satisfying conclusion.
