"Glow" by Amy Kathleen Ryan (St. Martin's Griffin, $17.99) Reviewed by Ealish Waddell As the two oldest children aboard the starship Empyrean, Kieran and Waverly always felt they were meant for each other.

Their home, a vast ark traveling through space, is the only world they've ever known, and all they expect to know until the day the ship finally reaches faraway New Earth and its mission to save the human race from extinction is completed.

Life on the Empyrean is peaceful and predictable. The most exciting thing to happen in years is the unexpected arrival of their sister ship, the New Horizon.

The Empyrean's passengers look forward to seeing new faces and meeting new friends. None of them expect the invasion.

In the blink of an eye, the Empyrean is crippled, hundreds are dead or missing, and all of the girls have been kidnapped. Whisked away on the New Horizon, 15-year-old Waverly and her friends find themselves under the control of its creepy captain, who seems to have a fanatical hold over most of the New Horizon's crew and something sinister in mind for her captives. Unwilling to believe all hope is lost, Waverly fights to sort out lies from truth and find a way to escape.

Back on the Empyrean, the remaining boys struggle with the loss of their parents and sisters and try to keep the ship running as best they can. Kieran, already trained for leadership, does his best to hold them together, but as dissent and distrust grow among the frightened kids, so do the fractures in their makeshift society.

Over the impossible miles, Kieran and Waverly long for each other, each using their love as inspiration to keep going through fear and despair.

But the things they must do to survive are taking their toll on their bodies and minds. If they finally see each other again, will they have changed beyond recognition?
