Coming April 2026

A starship captain and her crew face conspiracies and betrayals as they clash with various factions of a galactic civil war in a thrilling space adventure by New York Times bestselling author Mike Chen.

The starship Horizon’s crew spent ten years trapped across the expanse of space. Now they’re finally home—only it’s not the home they knew. The Cluster, once a peaceful coalition of planets, has fractured in the wake of civil war.Captain Demora Kim wants nothing more than to protect her surviving crew. It’s what she owes them after years of instability and terror. But in times of war, no one is allowed neutrality.

After an attack on a mining station leaves thousands dead, Demi’s efforts become almost impossible. Every ship is needed on the frontline. Thrust deeper into a conflict she barely understands, Demi considers a bold choice—one that might keep her promises but tip the galaxy further into chaos.

Mike Chen has done it again. He's turned theoretical physics inside-out to make you fall in love with a band of misfits from across the multiverse. The Photonic Effect is a delightful adventure, full of unexpected twists and wild rides, but, most of all, it's full of heart.
-- Annalee Newitz, bestselling author of Automatic Noodle and The Terraformers

"What space opera is meant to be. The Photonic Effect is a brilliantly complex novel about love, loss, and war that's populated by characters so alive you can feel their hearts in each beat of your own."
-- K.B. Wagers, author of A Pale Light in the Black

"Mike Chen expertly combines the challenges of a First Contact story with creditable alien-y aliens, problem-solving under extreme pressure, and a romance. It’s brilliant!"
-- Stina Leicht, author Persephone Station
