Doctor Who, meet Mr. Men: The Doctors from the popular sci-fi show will be made over in the style of the Mr. Men picture books.

There will be 12 books in the series, one per Doctor. The series will kick off with Dr. First, Dr. Fourth, Dr. Eleventh, and Dr. Twelfth, all to be published in 2017. Adam Hargreaves, the son of the late Mr. Men creator Roger Hargreaves, wrote and illustrated the books.
