Meg Medina has company!
Rainbow Rowell was ALSO recently uninvited from a speaking engagement:
Until we got involved in the issue, Rainbow Rowell couldn’t be 100% sure she had even been disinvited. The teachers and librarians had showed great enthusiasm at the outset, but as the date of her visit drew near, she was given mixed messages about her contract there and eventually came up against a communications freeze. A parent had lodged a challenge to profanity in the book and asked that the librarians who organized the talk to be punished. They riled up an action group (with experience in censorship) to organize against the author at the level of the County Board. The order came down. The talk was nixed and librarians were asked not to speak on the topic.
