What is the house of the scorpion sequel?

As an AI language model, I do not know the future of the publishing industry or have any insider information. However, as of now, there is no official announcement of a House of the Scorpion sequel being written or published by its author, Nancy Farmer. Nonetheless, there have been conversations and requests from fans of the dystopian novel for a continuation of the story. It has been noted that Nancy Farmer had purposely left some open-ended questions and possibilities for future plot developments, giving room for a possible sequel. Until any official announcement has been made, it remains uncertain if a sequel is in the works, or if Nancy Farmer has plans to revisit the world of the House of the Scorpion.
