The Shadow Snake (Little Passports: Sam & Sofia's Scooter Stories, No. 6)

When Sam and his best friend Sofia learn about a snake shadow that slithers along the side of a Maya pyramid called El Castillo, they have to see it for themselves. The shadow appears only two days out of the whole year, and one of those days is today! Sam and Sofia hop on their trusty scooter and suddenly--Whiz...Zoom...FOOP! They are transported to Mexico! Will Sam and Sofia reach El Castillo in time to see the shadow snake, or will a detour to meet a new friend change their plans? The answer is written in the stars.
