The Scarecrow of Oz — L. Frank Baum

In L. Frank Baum's “The Scarecrow of Oz” (1915), Cap'n Bill, a little girl named Trot, and Button-Bright from “The Road to Oz” are marooned in Jinxland, a mountainous region adjacent to Oz, but separated by a bottomless chasm. Here they get embroiled in a political rivalry between good King Kynd and the notorious usurper Krewl. When the Scarecrow gets wind of the trouble via Glinda's Great Book of Records (a kind of precursor to the internet) the fight between good and evil is joined. The ninth in the Oz books series, it was adapted from the 1914 silent film “His Majesty, the Scarecrow of Oz”.
