A Time Traveler's Theory of Relativity
Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books—and to his best friend, Gabi—to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time.
Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic.

Gray Matters
At 12 years old, Skeets Kalbfleischer is returning from a ski vacation when a lightning strike knocks his plane out of the sky, killing everyone else on board. Although his body is destroyed, a radical procedure preserves Skeets’s brain, which spends 25 years in a fish tank before mankind realizes the implications of his second life. A key to immortality has been found.
Four centuries later, it has become commonplace for the minds of the dead to be preserved. While warehoused in a massive storage facility tended by robots, the brains pass time watching old film clips, learning about bees, and meditating their way to a higher state of being. But for the facility’s overseers, Skeets presents a problem. A 12-year-old for all eternity, their most famous resident still wants to be a cowboy. To remedy this embarrassment, his handlers concoct a solution that will push humanity even farther past nature’s wildest dreams.

Weave a Circle Round
Freddy doesn’t want people to think she’s weird. Her family makes that difficult, though: her deaf stepbrother Roland’s a major geek, and her genius little sister Mel’s training to be the next Sherlock Holmes. All Freddy wants is to survive high school.
Then two extremely odd neighbors move in next door.
Cuerva Lachance and Josiah definitely aren't normal. Neither is their house, which defies the laws of physics. Neither is Freddy’s situation, when she suddenly finds herself stuck thousands of years in the past with her very, very weird neighbors. And that’s only the beginning.

The Mirror Man
The offer is too tempting: be part of a scientific breakthrough, step out of his life for a year, and be paid hugely for it. When ViMed Pharmaceutical asks Jeremiah to be part of an illegal cloning experiment, he sees it as a break from an existence he feels disconnected from. No one will know he’s been replaced—not the son who ignores him, not his increasingly distant wife—since a revolutionary drug called Meld can transfer his consciousness and memories to his copy.
From a luxurious apartment, he watches the clone navigate his day-to-day life. But soon Jeremiah discovers that examining himself from an outsider’s perspective isn’t what he thought it would be, and he watches in horror as “his” life spirals out of control. ViMed needs the experiment to succeed—they won’t call it off and are prepared to remove any obstacle. With his family in danger, Jeremiah needs to finally find the courage to face himself head-on.

Night Beast
In Night Beasts, author Ruth Joffre explores the lives of women—particularly queer women and mothers—and reveals the monsters lurking in our daily lives: the madness, isolation, betrayals, and regrets that arise as we seek human connection. Joffre takes readers to places where the sun never sets, where cornfields rustle ominously, and sleepwalkers prowl the night.
In “Weekend,” the lead actors of an avant-garde television show begin to confuse their characters’ identities with their own; in “Go West, and Grow Up,” a young girl living in a car with her mother is forced to shed her innocence too soon; and in “Safekeeping,” a woman trapped inside a futuristic safehouse gradually unravels as she waits for her lover, who may never return.

The Chaos Function
Olivia Nikitas, a hardened journalist whose specialty is war zones, has been reporting from the front lines of the civil war in Aleppo, Syria. When Brian, an aid worker she reluctantly fell in love with, dies while following her into danger, she’ll do anything to bring him back. In a makeshift death chamber beneath an ancient, sacred site, a strange technology is revealed to Olivia: the power to remake the future by changing the past.
Following her heart and not her head, Olivia brings Brian back, accidentally shifting the world to the brink of nuclear and biological disaster. Now she must stay steps ahead of the guardians of this technology, who will kill her to reclaim it, in order to save not just herself and her love, but the whole world.

Earthling
Orf is an intelligent drilling machine, designed to probe to the very center of the Earth. What he finds deep under the Earth's crust is a living force so radically unexpected that our life on the surface is altered by its discovery. But as the world around him changes, and the Pacific Northwest is transformed by cataclysmic earthquakes and social upheavals, Orf must change as well, becoming both myth and monster, savior and sage to future generations of humanity.

School for Sidekicks
Evan Quick has spent his whole life dreaming of becoming a hero. Every morning he wakes up and runs through a checklist of test to see if he's developed powers over night, and every day it is the same thing – nothing. No flying, no super strength, no heat rays or cold beams. No invulnerability—that always hurt to check—no telepathy, no magic. Not even the ability to light a light bulb without flipping a switch. And now, he's finally ready to give up.
But then, the class field trip to the Mask Museum is interrupted by a super villain attack, and Evan somehow manages to survive a death ray. Even better, Evan's favorite Mask, Captain Commanding, shows up to save them all—and when things go very wrong, it's Evan who finds the strength to come to Captain Commanding's rescue.
