This book is concurrent with Sunset (Pact Arcanum: Book 1) in story continuity.

Child of Twilight

Venice, Italy, 2039. When Michael Danvers witnesses a vampire attack, his latent ability to shapeshift awakens. Revealed as a Sentinel, the natural enemy of Nightwalkers, 13-year-old Michael must turn his back on his family and his safe, predictable life. But a supernatural battlefield is no place for a child, not even a genius like Michael. Betrayed by his own kind, he leaves Earth behind, hoping to find a new path with the Spacer Guild – and the stars.

Tempered by Moonlight

Relocating to the Citadel, Michael quickly makes a name for himself at the Spacer Guild Academy. But each advancement means less to him than the friendships he acquires, of fellow cadets William and Ariel, even as Michael is promoted above them.

Forged in Starlight

Everyone had plans for Michael’s future: his parents, the Sentinels, the Guild—even his best friend, Will. But Michael takes control of his destiny, and when called upon to make a fateful decision with countless lives hanging in the balance, the only sense of honor that matters is his own.
