Yesterday a memory popped into my head from a YA novel I'd read when I was very young. The novel was from the 70s or 80s, and the printing I owned had a yellow cover with a black and white photo on the front. The only thing about the novel I can remember is that it ended with the entire town chasing the protagonist's grandmother as she ran into the desert. When they finally found her she'd turned into a cactus. I think the novel was about plants who'd wanted to live with humans?
