This is book number 3 in the Dragons of Starlight series.
The mysteries unfold
As a Starlighter, Koren knows her destiny is to save her fellow human slaves from the dragons' bondage--but by following the orders of the smooth-talking dragon king, Taushin, has she in fact doomed her people and herself? As Koren struggles over her choices, Elyssa discovers a new aspect to her Diviner gifts when her pendant begins to unlock mysteries surrounding the stardrops from the Exodus star.
Soon Elyssa, along with Jason and his father, also uncovers new truths behind the dragons' prophecy and learns that Randall has teamed with Magnar and Arxad to wage battle against Taushin's followers. With a major war imminent and talk of a new Starlighter in the air, confusion and uncertainty reign--something Taushin might have planned for all along.
