Slangerup answers children who want to know how Santa got his start, why he lives at the North Pole, what he does in the off-season, what’s with the jingle bells, and similar holiday FAQs. Mrs. Claus offers a scrapbook crowded with news clippings (“Santa wins fifteenth consecutive sleigh race”), torn-out advertisements, corporate publications (“Elfployee of the Month”), mementoes, memos, snapshots, and similar detritus, all linked by her own affectionate commentary, written on an assortment of large gift tags. From a view of Santa’s driver’s license and Naughty/Nice database to the real story behind that “Ho-Ho-Ho!” (he was really saying Whoa! Whoa! Whoa!), this faux-collage-illustrated album will give young readers the real scoop on one of the planet’s hardest-working guys. (Picture book. 7-9)
