Our take
Award-winning author Kameron Hurley delivers a 4.4-star sci-fi mindwarp in The Light Brigade, a gritty military thriller where soldiers are transformed into particles of light—and time itself is a weapon. Think Starship Troopers meets Slaughterhouse-Five, with more rage, trauma, and corporate corruption. If you like your sci-fi wild, smart, and devastating, enlist now.

About the book
War turns soldiers into light—literally.
In the corporate-run war against Mars, infantry grunts are broken down into particles and beamed to distant battlefronts. Most return changed. Some don’t return at all. But when fresh recruit Dietz starts dropping into battles that don’t align with mission briefings, something becomes terrifyingly clear: reality is out of sync.
Each combat drop reveals pieces of a war that isn’t what it seems—and a truth the corporate brass would kill to keep buried. As Dietz spirals through time, memory, and mayhem, survival means more than following orders. It means questioning everything.
From Hugo Award winner Kameron Hurley, The Light Brigade is a mind-bending sci-fi thriller that blends military grit with temporal chaos in a blistering indictment of war, loyalty, and corporate control.

"A Memory Called Empire perfectly balances action and intrigue with matters of empire and identity. All around brilliant space opera, I absolutely love it."—Ann Leckie, author of Ancillary Justice
Ambassador Mahit Dzmare arrives in the center of the multi-system Teixcalaanli Empire only to discover that her predecessor, the previous ambassador from their small but fiercely independent mining Station, has died. But no one will admit that his death wasn't an accident—or that Mahit might be next to die, during a time of political instability in the highest echelons of the imperial court.
Now, Mahit must discover who is behind the murder, rescue herself, and save her Station from Teixcalaan's unceasing expansion—all while navigating an alien culture that is all too seductive, engaging in intrigues of her own, and hiding a deadly technological secret—one that might spell the end of her Station and her way of life—or rescue it from annihilation.
Arkady Martine's debut novel A Memory Called Empire is a fascinating space opera and an interstellar mystery adventure.
"The most thrilling ride ever. This book has everything I love."—Charlie Jane Anders, author of All the Birds in the Sky

About the book
Jack Morgan is a teenage fugitive with a price on his head. Draycos is a dragonlike alien warrior who lives on Jack’s skin as a golden, ever-shifting tattoo.
Together, they’ve survived mercenaries, space battles, and near-death missions. Now they’re infiltrating a Brummga estate—posing as slave and property—to expose a conspiracy threatening Draycos’s entire species.
Jack’s mission? Hack the estate’s computer system, avoid blowing his cover, and not get killed by the brutal overseer who thinks pain is the best motivator.
It’s dangerous. It’s dirty. And it’s their only shot at finding the truth.
In this third Dragonback adventure from Timothy Zahn, loyalty runs deep, the stakes are sky-high, and freedom may cost more than either of them is ready to pay.

Choose your retailer
About the book
The New York Times Bestselling series is now available in Kindle Unlimited for the first time and includes an exclusive NEW novella at the end.
They dive so humanity survives…
More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers—men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.
When one of the remaining airships is damaged in an electrical storm, a Hell Diver team is deployed to a hostile zone called Hades. But there’s something down there far worse than the mutated creatures discovered on dives in the past—something that threatens the fragile future of humanity.
