Fire is a good servant but a bad master

This is a sequel to fighting fire with fire! If you haven't read the first book, I'd advise you to.

It has been 500 years since purple diamond's accidental shattering. She was replaced by another half-gem, green diamond. But as the conquest of the universe begins once more and Lavender is gifted with earth, will she succeed where past diamonds have failed? Or will the guilt of loosing a friend finally consume her? As she fights her personal demons, her fellow half-diamonds and white diamond herself, she learns that she's far more powerful than she believes she is.
