Booklist, in its review of
The Clone Codes, wrote "The McKissacks' slight story for younger readers packs a great deal of messaging, which will no doubt prove useful in classroom discussions of issues and themes but sometimes comes at the expense of the story. The science-fiction backdrop serves as a framework for issues of identity and societal prejudice but is not predominant in the reading experience."
