The Twelve Bots of Christmas, written and illustrated by Nathan Hale, Walker Books, $14.99, ages 4-8, 40 pages. Stand to the side, true love. Robo Santa's got his own gifts for The Twelve Days of Christmas. In this clever techno-twist on the classic English Christmas carol, gizmos fly, roll, swim and snooze before being packed into a sack for Robo Santa and his eight super-charged reindeer to deliver to little boys and girls. You'll be sold from the first verse, A "Cartridge in a Gear Tree," and by the time you belt out "Five Bot-to-Ries," the rest of the family will be chiming in too. "Four Calling Borgs, Three Wrench Hens, Two Turbo-Doves, and a Catridge in a Gear Tree..." My favorite image: The Three Wrench Hens bobbing their hook jaws as they roll through the snow.
