Parent and child share a day of small adventures and cozy snuggles.That the two happen to be tortoises is totally beside the point. Die-cut holes and shaped edges turn nearly every page flip into a surprise. Following a parental "Good morning, Baby" to greet the youngling's "Wake up, wake up, I want to play… / The sun is up, it's a brand new day!" the two reptiles ramble off to munch on leaves, weather a sudden rain shower, discover a flock of butterflies, climb a hill, watch the moon rise, and, at last, weary little one perched on top, settle down to snooze again. The paper engineering is ingenious. Turning a seemingly arbitrarily shaped page with a special window framing a pink butterfly fills the spread with many jewel-toned insects; even though the tortoises never change position, the scene is completely transformed. Hegarty's rhymed narrative features lots of tender sentiments-"Wherever you are, wherever you go, / Baby, I'll always love you so"-while steering clear of any gender references. In Elliott's peaceful, grassy settings the wanderers' small smiles and shared glances likewise create a sense of loving intimacy. This is likely to become a victim of its own appeal, being as the paper stock is rather too flimsy to survive much contact with toddler hands. Still, a clear winner for sharing with audiences of one or dozens.Guess how much you'll be reading this. (Novelty. 18 mos.-3)
