Publisher's Synopsis
Rayn, Jo-Jo, Yubi, Catori and Fernanda were born on the March 4th, at the same time, but in different parts of the world. They are given a ring with a musical instrument on it for their eighth birthday with instructions to put the ring on their left ring finger at exactly the time that they were born. Once they put the ring on, they are zapped to the portal at 1 South Boston Avenue, Tulsa, Oklahoma 74103 which is the center of the universe. When they get there, they meet Aura who is the female voice in the portal who instructs them to insert the instrument that is on their ring into the portal at the same time which will take them back in time to meet different historical women. The girls travel through time with Yubi's panda named Blinko and Jo-Jo's kitten named Kitty-Paws. On this journey, they learn about Sarah Breedlove known to us as Madam C.J. Walker, Stephanie Kwolek, Cher Wang, Dr. Susan La Flesche Picotte, and Selena Quintanilla-Perez.
