Destiny's War - The First Star, #3

She had given her up. To save her daughter from a life of servitude to a silent First Star, Layela Delamores sent her only child away. Willing to miss the first decade of her daughter's life, for a chance to reunite as a free family. Ten years. Now, a new First Star is ready to take over from the dying star Mirial, freeing Layela and her family from the clutches of duty and obligation. But the star was silent.
When the new First Star fails to ignite, the failing Mirial is the only lifeline to the countless ether races across the galaxy. But not everyone wants to save Mirial, including Layela's own daughter. Trapped between obligations and hopes, Layela must find a way to save as many people as she can, or learn to live in the dead world she helped to create.
