I got a little behind with Lory’s group read of the Oz books but here are two more, slightly out of order:
Tik-Tok of Oz (1914). This book starts off in an obscure part of Oz called Oogaboo, where a dissatisfied young woman called Ann Soforth decides to muster an army and go conquer the rest of Oz. Elsewhere, Betsy Bobbin and Hank the mule, wash up from Oklahoma into the Rose Kingdom, a land bordering Ev (see Ozma of Oz) and the Nonestic Ocean, where they meet our old acquaintance, the Shaggy Man, searching for his brother who was captured by the Nome King.
