Title: Blizzard of the Blue Moon
Publication Info: New York : Random House, c2006.
This may be my favorite Magic Tree House book yet. Jack and Annie are sent to Depression-era New York City to find a unicorn (SPOILER: If you didn’t guess, it’s in the Cloisters museum, although there’s a great diversion where Jack & Annie try to go to the Bronx Zoo). Jack & Annie take a subway and a cab on their quest as they have to fight against a blizzard and a pair of dark wizards en route to their goal. What’s great about this book is that the fantasy and adventure elements are blended so well with an honest portrayal of the poverty and desperation of the Depression.
