Scott Stanford - Dorothy-The Darker Side Of Oz [Kindle azw3]

As Dorothy awakes in Oz there's no sunshine in Munchkin country, just a twisted race enslaved by the Eastern witch, and a crooked path of yellow bricks she has to take to the mysterious Emerald City, a place ridden with sinister secrets. To get home the orphan girl treks the magical land, sometimes beautiful though often deadly, seeking help from the great wizard of Oz.
