Retrograde: The Darkness (Hardcover) (ISBN-13: 9781735355504)

Life on Damara stands on the brink of destruction...

Isis Pnina Mahmoud, daughter of the President of Cairo, leads a privileged life, but it's not what she wants.

She longs for purpose.

Purpose finds her when the mighty Retrograde threatens to destroy her planet. To fend off a devastating attack, Isis defies her mother's wishes and joins the army.

Joined in battle by the mysterious and enigmatic Khalfani Abaza, she finds herself drawn to him in inexplicable ways. As the Retrograde barrels down on them, the force that pulls her closer grows stronger.

When they join forces with Aurora, a fearless military brigade leader, the mystery behind their magnetic connection slowly unfolds, but only at Aurora's will and on her terms.

The trio must rely on each other to survive a near-impossible mission. If they fail, Damara's very existence will be no more.
