Legend of the Pricklepeople A Short Story by Granny Which Witch and Plagiarized Shamelessly by PS Wright
Carnegiea Saguaro travels to the mountains to make an alliance with the mountain Pines against the Agaves. Joshua Tree, sends her to the top of the mountain to hum the witch away.
Joshua Agave thinks himself clever, but in the end, the joke may be on him. The fate of the pricklepeople and their human friends lays in the balance when the winter witch demands a blossom more beautiful than Datura.
