Day of the Black Blizzard [PDF ebook] 

Ten-year-old Orry Jenkins is sick and tired of the dust. The year is 1935 and Kansas hasn’t gotten enough rain in years. Instead of rainstorms, they get dust storms. One day, Orry and his little stepsister go outside to play. They’re far from home when a huge dust storm comes up. Stranded alone on the plains, the children must find a way to survive the terrible black blizzard.
