Zenna Henderson wrote of this ability to warm a cup by concentrating on it. I loved her stories.
It is surmised that her stories of “The People” were the precursors for the Disney “Witch Mountain” series.
It could be, but the matter was never litigated. Her stories still hold their value, though.
Interesting! I never paid attention to the “Witch Mountain” series, but enjoyed Zenna Henderson’s stories way back when.
