Naledi is a normal 12 year old girl living in Maun Botswana —normal, that is, until the day Oratile, her bully at school, notices the three scars she has on her arm, scars she got on the day her mother died. Oratile recognizes those scars because she has them too! But how can that be? Slowly the truth about what those scars mean is revealed—Naledi, just like Oratile, is one of the Lionesses, secret female superheroes fighting to keep Earth and its people safe from evil. Her mother gave her those scars as she was dying so that she could pass her Lioness powers to Naledi. Meanwhile, Sheridan, Naledi’s best friend, has uncovered a secret group of scientists working in Maun, the SES, who are working on Earth’s most pressing problems. They’ve developed a forever-energy-producing object, a green diamond, which can solve all of Earth’s energy needs. It seems like a good thing, but if it gets into the wrong hands it could be a very big problem. Unfortunately, the wrong hands are on their way to Earth for that very reason.
Naledi quickly starts learning how to be a Lioness but the time is short because evil is coming! That evil is in the form of Verril, an alien leader from the planet Kepler C, who has a single objective: to take over the entire Universe. The problem is Verril needs energy to power her superweapons that will ensure in battle she and the Keplerians will always be the victors. She is coming to Earth to get the forever-energy producing green diamonds. If she’s successful, the end of The Universe, including Earth, will not be far behind. The Lionesses are the only ones who can stop Verril from getting the green diamonds. Naledi will risk nearly everything to keep the green diamonds out for Verril’s evil hands…the question is: will that be enough to save the Universe?
