The first in an all-new fantasy series from rising star David Dalglish.

The last remnants of humanity live on six islands floating high above the Endless Ocean, fighting a brutal civil war in the skies. The Seraphim, elite soldiers trained for aerial combat, battle one another while wielding elements of ice, fire and lightning.

The lives of their parents claimed in combat, twins Kael and Breanna Skyborn enter the Seraphim Academy to follow in their footsteps. They will learn to harness the elements as weapons and fight at break-neck speeds while soaring high above the waters. But they must learn quickly, for a nearby island has set its hungry eyes on their home. When the invasion comes, the twins must don their wings and ready their blades to save those they love from annihilation.
