If you were heading to London, would you hop on the Tube to visit Buckingham Palace, find a tasty lunch on Brick Lane, or pass the time with Big Ben? Armchair travelers ages 4 to 8 can create an itinerary, choose which places to visit at the end of every page, and follow along with an adventurous girl and her moms as they explore London. Holly Maher's illustrations abound in familiar details, and the book concludes with additional info on such sites as the Thames, Westminster Abbey, the Globe Theatre, Tate Modern, Kings Cross Station, and Stonehenge.
