Princess Shlilah and the Thorachini

Princess Shlilah is taken from Earth to the planet of Thoracen where her mission is to help the children of Thoracen to retrieve the adults Thorachini from the Jarahaliis. Because the Jarahaliis have crossed over universes in order to find a better place to live they need the Thorachini to copy and assimilate with their DNA in order to survive on Thoracen. But Princess Shlilah as directed by the doves of Thoracen must prevent the Jarahaliis from completing their mission.
