Ouroboros

James S. A. Corey - Tiamat's ​Wrath
Thirteen ​hundred gates have opened to solar systems around the galaxy. But as humanity builds its interstellar empire in the alien ruins, the mysteries and threats grow deeper. In the dead systems where gates lead to stranger things than alien planets, Elvi Okoye begins a desperate search to discover the nature of a genocide that happened before the first human beings existed, and to find weapons to fight a war against forces at the edge of the imaginable. But the price of that knowledge may be higher than she can pay. At the heart of the empire, Teresa Duarte prepares to take on the burden of her father's godlike ambition. The sociopathic scientist Paolo Cortázar and the Mephistophelian prisoner James Holden are only two of the dangers in a palace thick with intrigue, but Teresa has a mind of her own and secrets even her father the emperor doesn't guess. And throughout the wide human empire, the scattered crew of the Rocinante fights a brave rear-guard action against Duarte's authoritarian regime. Memory of the old order falls away, and a future under Laconia's eternal rule -- and with it, a battle that humanity can only lose - seems more and more certain. Because against the terrors that lie between worlds, courage and ambition will not be enough...

Frank Herbert - Dune ​(angol)
This ​Hugo and Nebula Award winner is widely to be considered the most prescient SF novel ever. It tells the sweeping tale of a desert planet called Arrakis, the focus of an intricate power struggle in a byzantine interstellar empire. Arrakis is the sole source of Melange, the "spice of spices." Melange is necessary for interstellar travel and grants psychic powers and longevity, so whoever controls it wields great influence. The troubles begin when stewardship of Arrakis is transferred by the Emperor from the Harkonnen Noble House to House Atreides. The Harkonnens don't want to give up their privileges, however, and through sabotage and treachery they cast young Duke Paul Atreides out into the planet's harsh environment to die. There he falls in with the Fremen, a tribe of desert dwellers who become the basis of the army with which he will reclaim what's rightfully his. Paul Atreides, though, is far more than just a usurped duke. He might be the end product of a very long-term genetic experiment designed to breed a super human; he might be a messiah. His struggle is at the center of a nexus of powerful people and events, and the repercussions will be felt throughout the Imperium.

Stephen King - Wolves ​of the Calla
Roland ​Deschain and his ka-tet are bearing southeast through the forests of Mid-World, the almost timeless landscape that seems to stretch from the wreckage of civility that defined Roland's youth to the crimson chaos that seems the future's only promise. Readers of Stephen King's epic series know Roland well, or as well as this enigmatic hero can be known. They also know the companions who have been drawn to his quest for the DarkTower: Eddie Dean and his wife, Susannah; Jake Chambers, the boy who has come twice through the doorway of death into Roland's world; and Oy, the Billy-Bumbler. In this long-awaited fifth novel in the saga, their path takes them to the outskirts of Calla Bryn Sturgis, a tranquil valley community of farmers and ranchers on Mid-World's borderlands. Beyond the town, the rocky ground rises toward the hulking darkness of Thunderclap, the source of a terrible affliction that is slowly stealing the community's soul. One of the town's residents is Pere Callahan, a ruined priest who, like Susannah, Eddie, and Jake, passed through one of the portals that lead both into and out of Roland's world. As Father Callahan tells the ka-tet the astonishing story of what happened following his shamed departure from Maine in 1977, his connection to the Dark Tower becomes clear, as does the danger facing a single red rose in a vacant lot off Second Avenue in midtown Manhattan. For Calla Bryn Sturgis, danger gathers in the east like a storm cloud. The Wolves of Thunderclap and their unspeakable depredation are coming. To resist them is to risk all, but these are odds the gunslingers are used to, and they can give the Calla-folken both courage and cunning. Their guns, however, will not be enough.
