Powers Unleashed - The Mystical Diamond, #2

Nearly twenty years after the quintuplets recovered the Mystical Diamond and saved the world from the evil powers of Alaric Whiteman, he's back for revenge, bigger, stronger, and more determined than ever to meet his goal. However, attempting to take over the world once again is no small feat, entrancing Astraea to the side of evil and turning her into a formidable opponent. The remaining siblings, Zaina, Sage, and Cristiano find themselves in the unenviable position of saving the world while keeping their family safe from harm.
Will the quintuplets succeed this time, or will this power struggle sever their family ties for good, in Powers Unleashed?
