About the book
When aliens invade, a generations-long struggle begins against an impenetrable enemy in this sci-fi epic from the Hugo and Nebula Award–winning author.
The Entities have arrived on Earth, fifteen feet tall with impenetrable defenses and inscrutable motives. As conquerors, they have no demands, no explanations, simply harsh consequences should they be challenged. Releasing a plague and plunging the world into a new Dark Age, the Entities seem unbeatable. But, one family at least—the Carmichael clan led by Colonel Anson Carmichael—will never give up the resistance.
THE ALIEN YEARS is an epic story told over multiple generations by master of thoughtful science fiction Robert Silverberg. Can ideas of freedom survive in the face of an overwhelmingly powerful enemy? "A remarkable study of human endurance and patience that belongs in most SF collections." —The Library Journal
"Sobering and frightening…. Silverberg's rich characters, his dead-on-target vision of modern society, his mastery at building tension—all are in evidence in this notable outing from one of the very best." —Publishers Weekly

Our take

About the book
They escaped the deep. But the horror followed them to the surface.
After surviving a nightmare beneath the ocean on the USS Challenger, three crew members thought the worst was over. They were wrong. The experiment that created a new life form—engineered from bacteria that thrive in volcanic ocean vents—wasn’t just a failure. It was an evolution.
Now the creatures have surfaced. They're faster. Smarter. And hungrier.
A Japanese trawler is a floating graveyard. A luxury yacht is torn apart. A Coast Guard crew is slaughtered. The infection is spreading—and it all began with one man’s dream of reaching Mars.
Dark Tide Rising is a relentless sci-fi horror sequel from deep-sea expert David M. Salkin. If you thought the nightmare ended in Deep Black Sea… it’s only just begun.

About the book
A masterpiece ahead of its time, a prescient rendering of a dark future, and the inspiration for the blockbuster film Blade Runner
By 2021, the World War has killed millions, driving entire species into extinction and sending mankind off-planet. Those who remain covet any living creature, and for people who can’t afford one, companies built incredibly realistic simulacra: horses, birds, cats, sheep. They’ve even built humans. Immigrants to Mars receive androids so sophisticated they are indistinguishable from true men or women. Fearful of the havoc these artificial humans can wreak, the government bans them from Earth. Driven into hiding, unauthorized androids live among human beings, undetected. Rick Deckard, an officially sanctioned bounty hunter, is commissioned to find rogue androids and “retire” them. But when cornered, androids fight back—with lethal force.

About the book
Sergeant Gastovsky—Gas to everyone except his superiors—never planned on joining the military. But when a con gone sideways lands him in power armor, he figures he might as well make it work… and maybe work a few side hustles while he’s at it.

It’s Ocean’s Eleven in space—with bullets, betrayal, and the best kind of bad decisions.
