Incandescence

Doella wonders what she is and looks for the answers she already knows. In this final book we find out, and the truth is not easy for any of us. She meets the Cael, the oldest creature in the universe, and finally learns the truth of her making and the terror of her ending, both of which she has stubbornly refused to admit. She bears the children the Elder Vrash has foretold, and in doing so unleashes a power as great as her own on the universe - for these are the Discuri, the twins. These two sons of Doella must fight, one for good and one for evil. Evil must destroy all those who value goodness, for it cannot bear the light. Doella must locate the other Guardians if she is to hold this universe for the side of light and for the futures yet to come. In this final book we share with Doella the truth of her terrible existence and why she must be the "mother of all."
