We Are Light and Glory

Take a deep breath and begin the fourth and final installment of the Calladon Chronicles. They conclude in this sweeping, fast-paced, gasp-out-loud-in-disbelief book that pulls from your emotions to weave its story.
With the fate of past and present contingent on her choices, Kal makes a final confrontation against the Dark that holds a fractured world on the edge of oblivion. With her past returned to her, and as the next Seer, she refuses to give up, no matter the cost. She's already paid too high a price to back down.
But she soon discovers that Light will only triumph if she is willing to sacrifice more. More than she could have ever thought possible.
And she finds that the greatest battle one can face is against oneself.
Is it all worth it in the end for a human to have tried?
