Creators [PDF ebook] 

The Shanji Trilogy, which began with Shanji and Empress of Light, comes to its stunning conclusion with this tale of three generations of Creators. Kati, the light-wielding genetic changeling who saved her planet and became its empress, is now threatened with assassination. Yesui, Kati’s daughter who came to control mass as well as light, faces revolution and learns the uses of diplomacy. And Bao and Shaan, Yesui’s twin daughters, take the lineage to its limit. Leaving their universe behind, they spin forth a radiant new creation.
