A great deal of warmth permeates this lovely story of the cold arctic and a polar bear cub’s first exploration outside the cave in which he was born. The golden tinge given to his and his mother’s fur plays off the cool blues and greens Cepeda uses to depict snow, sea water, and the aurora borealis. Playful movements and the swirl of Cepeda’s thickly applied paint will lead little eyes through cub’s adventures slipping down icy slopes and running across the ice as he pursues a fox and a seal. The picture book’s simple plot—the cub loses sight of his mom in the great wide open and thereby realizes the nature of the world’s vastness—ends reassuringly for lap-sitters when the two are reunited. The message mother bear delivers (“The world is big. I’ll be close by till you’re big, too”) is comforting, as is the final frame depicting mother and child curled together in sleep. A nice addition to collections for the youngest tots, who will agree with Thomson that “Cub’s world was good.” Preschool-Kindergarten. --Karen Cruze
"Thomson's personification of Mom and Cub, along with her measured, soothing text, make for an agreeable, affirming story for both one-on-one and group sharing."
"The suspense is toddler-perfect, with Mom appearing the moment it all become's too much. . . Lap-sit ready, with a built-in hug at the end."
—The Horn Book Magazine
"Thomson's calm voice makes it clear that Mom's absence is only temporary, so readers can snuggle up and relish this big polar world, gorgeously and inventively imagined."
