Our take
Gideon the Ninth throws swordplay, necromancy, and gallows humor into a gothic sci-fi blender. Trapped serving her bone-witch nemesis, Gideon joins a lethal trial where immortal power is the prize and betrayal is guaranteed.

The Emperor needs necromancers.
The Ninth Necromancer needs a swordswoman.
Gideon has a sword, some dirty magazines, and no more time for undead nonsense.
Tamsyn Muir’s Gideon the Ninth unveils a solar system of swordplay, cut-throat politics, and lesbian necromancers. Her characters leap off the page, as skillfully animated as arcane revenants. The result is a heart-pounding epic science fantasy.
Brought up by unfriendly, ossifying nuns, ancient retainers, and countless skeletons, Gideon is ready to abandon a life of servitude and an afterlife as a reanimated corpse. She packs up her sword, her shoes, and her dirty magazines, and prepares to launch her daring escape. But her childhood nemesis won’t set her free without a service.
Harrowhark Nonagesimus, Reverend Daughter of the Ninth House and bone witch extraordinaire, has been summoned into action. The Emperor has invited the heirs to each of his loyal Houses to a deadly trial of wits and skill. If Harrowhark succeeds she will be become an immortal, all-powerful servant of the Resurrection, but no necromancer can ascend without their cavalier. Without Gideon’s sword, Harrow will fail, and the Ninth House will die.

About the book
Finalist for the International Booker Prize and the National Book Award
A haunting Orwellian novel about the terrors of state surveillance, from the acclaimed author of The Housekeeper and the Professor.
On an unnamed island, objects are disappearing: first hats, then ribbons, birds, roses. . . . Most of the inhabitants are oblivious to these changes, while those few able to recall the lost objects live in fear of the draconian Memory Police, who are committed to ensuring that what has disappeared remains forgotten. When a young writer discovers that her editor is in danger, she concocts a plan to hide him beneath her floorboards, and together they cling to her writing as the last way of preserving the past. Powerful and provocative, The Memory Police is a stunning novel about the trauma of loss.

Vicious
V.E. Schwab
Fantasy · Sci-Fi · Travis' Picks
Our take
Called “Fresh, merciless, and, yes, vicious. Wow.” by Mira Grant, Vicious follows former college roommates Victor and Eli, whose experiments with extraordinary abilities leave them enemies pursuing competing ideas of revenge and justice. Best for readers who like morally gray characters, superpowers, former friends turned enemies, and dark revenge-driven fantasy.
Choose your retailer
About the book
V. E. Schwab's New York Times bestseller Vicious is a masterful tale of ambition, jealousy, desire, and superpowers.
Victor and Eli started out as college roommates—brilliant, arrogant, lonely boys who recognized the same sharpness and ambition in each other. In their senior year, a shared research interest in adrenaline, near-death experiences, and seemingly supernatural events reveals an intriguing possibility: that under the right conditions, someone could develop extraordinary abilities. But when their thesis moves from the academic to the experimental, things go horribly wrong.
Ten years later, Victor breaks out of prison, determined to catch up to his old friend (now foe), aided by a young girl whose reserved nature obscures a stunning ability. Meanwhile, Eli is on a mission to eradicate every other super-powered person that he can find—aside from his sidekick, an enigmatic woman with an unbreakable will. Armed with terrible power on both sides, driven by the memory of betrayal and loss, the archnemeses have set a course for revenge—but who will be left alive at the end?
In Vicious, V. E. Schwab brings to life a gritty comic-book-style world in vivid prose: a world where gaining superpowers doesn't automatically lead to heroism, and a time when allegiances are called into question.
"A dynamic and original twist on what it means to be a hero and a villain. A killer from page one…highly recommended!" —Jonathan Maberry, New York Times bestselling author of Marvel Universe vs The Avengers and Patient Zero

Choose your retailer
About the book
#1 New York Times bestselling master of suspense Dean Koontz takes a surprising and exhilarating road trip with a man in pursuit of his strange past—mile by frightening mile.
Quinn Quicksilver was born a mystery—abandoned at three days old on a desert highway in Arizona. Raised in an orphanage, never knowing his parents, Quinn had a happy if unexceptional life. Until the day of “strange magnetism.” It compelled him to drive out to the middle of nowhere. It helped him find a coin worth a lot of money. And it practically saved his life when two government agents showed up in the diner in pursuit of him. Now Quinn is on the run from those agents and who knows what else, fleeing for his life.
During a shoot-out at a forlorn dude ranch, he finally meets his destined companions: Bridget Rainking, a beauty as gifted in foresight as she is with firearms, and her grandpa Sparky, a romance novelist with an unusual past. Bridget knows what it’s like to be Quinn. She’s hunted, too. The only way to stay alive is to keep moving.
Barreling through the Sonoran Desert, the formidable trio is impelled by that same inexplicable magnetism toward the inevitable. With every deeply disturbing mile, something sinister is in the rearview—an enemy that is more than a match for Quinn. Even as he discovers within himself resources that are every bit as scary.

Welcome to the Saloon Sector, Deputy—try not to break the place.
Thelma Bach graduated top of her class at the Galactic Justice Academy. But as a Rock Sector citizen, she was never meant to succeed. To remind her of her place, the core worlders ship her off to the despised frontier, the lawless Saloon Sector.
They picked the wrong woman to push around.

She’ll outmaneuver her enigmatic sheriff (who happens to be her Star Marine brother’s old comrade), win over artificial intelligences, take down bandits, and out-negotiate aliens. Surviving her exile won’t be the problem—the real question is whether the Saloon Sector will survive her.

About the book
Moving to small-town West Virginia was supposed to be boring. Then I met my neighbor.
Daemon Black is infuriating. Arrogant. Too gorgeous for his own good. And 100% not worth my time. But when a stranger attacks me and Daemon literally freezes time with a wave of his hand, my life takes a sharp detour into the impossible.
Daemon is an alien. A ridiculously powerful, ridiculously annoying alien. And now, thanks to his interference, I’m glowing like a human beacon for every enemy in the galaxy. Sticking close to him is my only chance of survival.
Too bad we can’t stand each other.
A sizzling, action-packed romance with jaw-dropping twists, Obsidian is the start of an addictive, out-of-this-world series that will leave you breathless.

About the book
“Planetside is a smart and fast-paced blend of mystery and boots-in-the-dirt military SF that reads like a high-speed collision between Courage Under Fire and Heart of Darkness.” – Marko Kloos, bestselling author of the Frontline series
A seasoned military officer uncovers a deadly conspiracy on a distant, war-torn planet…
War heroes aren't usually called out of semi-retirement and sent to the far reaches of the galaxy for a routine investigation. So when Colonel Carl Butler answers the call from an old and powerful friend, he knows it's something big—and he's not being told the whole story. A high councilor's son has gone MIA out of Cappa Base, the space station orbiting a battle-ravaged planet. The young lieutenant had been wounded and evacuated—but there's no record of him having ever arrived at hospital command.
The colonel quickly finds Cappa Base to be a labyrinth of dead ends and sabotage: the hospital commander stonewalls him, the Special Ops leader won't come off the planet, witnesses go missing, radar data disappears, and that’s before he encounters the alien enemy. Butler has no choice but to drop down onto a hostile planet—because someone is using the war zone as a cover. The answers are there—Butler just has to make it back alive…
“Not just for military SF fans—although military SF fans will love it—Planetsideis an amazing debut novel, and I’m looking forward to what Mammay writes next.” – Tanya Huff, author of the Confederation and Peacekeeper series
