In the first of book of the series, Just Imagine...What If There Were No Black People in the World? Jaxon, a 4th grader, discovers that the necklace his grandmother gave him before she passed away has magical powers. With the magical necklace and saying the magic words, 'just imagine', he can see and talk with African American inventors and scientists. Jaxon is also playing the role of Dr. Martin Luther King in the school play in celebration of Black History Month. However, Jaxon stutters when he is in front of a crowd and when he meets new people. He hopes he can find a way to overcome his problem with stuttering before the day of the play.
Jaxon learns that his sister had the necklace before Jaxon and shares the rules of the necklace. She tells him that he can only use the necklace three times in a month; he will only be able to use the necklace until he is 16; never take off the necklace and be careful what he wishes for.
After Jaxon makes his second wish, he learns what his sister meant when she said to be careful what he wishes for. Can Jaxon get out of his mess before his parents find out? Does he bomb on the day of the play?
Jaxon will learn that sometimes you can overcome a problem if you don't spend a lot of time worrying about it.
