The Casaday Girls, Book 1: Super Kids [EPUB ebook] 

Sisterhood can be a love-hate relationship, especially when you deal with the competitive spirit of pre-teens–kids who just happen to possess superpowers. So it goes with Alexa (age twelve) and ten-year-old Rachael Casaday, seemingly ‘normal’ sisters with special gifts handed down from previous generations. In BOOK 1: SUPER KIDS, they will need these powers, not to mention the love and support of each other if they are to even survive this tale of wickedness and deception. The forces of evil are out there–a threat to their family, the community, and ultimately the lawmakers of our country. Leave it to the Casaday girls to derail this diabolical plan.
