Grieving her best friend's recent death, neuroscientist Mariana Pineda is ready to give up everything to start anew. Even her career --- after one last week consulting at a top-secret particle accelerator. Except the strangest thing happens: a man stops her and claims they've met before. Carter Cho knows who she is, why she's mourning and why she's there. And he needs Mariana to remember everything he’s saying. Because time is about to loop. In a flash of energy, it’s Monday morning. Again. Together, Mariana and Carter enter an inevitable life, four days at a time, over and over, without permanence except for what they share. But just as they figure out this new life, everything changes. Because Carter's memories of the time loop are slowly disappearing. And their only chance at happiness is breaking out of the loop --- forever.

Everything you’ve heard about vampires is a lie. They can’t fly. No murders allowed (the community hates that). And turning into a bat? Completely ridiculous. In fact, vampire life is really just a lot of blood bags and night jobs. For Louise Chao, it’s also lonely since she swore off family ages ago. At least she’s gone to decades of punk rock shows. And if she can join a band of her own (while keeping her...situation under wraps), maybe she’ll finally feel like she belongs, too. Then a long-lost teenage relative shows up at her door. Whether it’s Ian’s love of music or his bad attitude, for the first time in ages, Louise feels a connection. But as Ian uncovers Louise’s true identity, things get dangerous --- especially when he asks her for the ultimate favor.

Evie Shao and her sister, Kass, aren’t on speaking terms. Fifteen years ago on a family camping trip, their father and brother vanished. Their dad turned up days later, convinced he'd been abducted by aliens. Their brother, Jakob, remained missing. Kass suspected that her college-dropout twin simply ran off, while Evie traded academics to pursue alien conspiracy theories, always looking for Jakob. When Evie's UFO network uncovers a new event, she goes to investigate. And discovers Jakob is back. He's older, stranger and talking of an intergalactic war, but the tensions between the siblings haven't changed at all. If the family is going to come together to help Jakob, then Kass and Evie are going to have to fix their issues, and fast.

Jamie woke up in an empty apartment with no memory and only a few clues to his identity, but with the ability to read and erase other people’s memories --- a power he uses to hold up banks to buy coffee, cat food and books. Zoe is also searching for her past, and using her abilities of speed and strength…to deliver fast food. And she’ll occasionally put on a cool suit and beat up bad guys, if she feels like it. When the archrivals meet in a memory-loss support group, they realize the only way to reveal their hidden pasts might be through each other. As they uncover an ongoing threat, suddenly much more is at stake than their fragile friendship.

Six years after a virus wiped out most of the planet’s population, former pop star Moira is living under a new identity to escape her past --- until her father launches a sweeping public search for her. Desperate for a fresh start herself, jaded event planner Krista navigates the world for those still too traumatized to go outside. Rob has tried to protect his daughter, Sunny, by keeping a heartbreaking secret, but when strict government rules threaten to separate parent and child, Rob needs to prove himself worthy in the city’s eyes by connecting with people again. The lives of Krista, Moira, Rob and Sunny begin to twine together. When reports of another outbreak throw the fragile society into panic, the friends are forced to finally face everything that came before --- and everything they still stand to lose.

Torn between two lives, Kin is desperate for a way to stay connected to both. But when his best efforts threaten to destroy the agency and even history itself, his daughter’s very existence is at risk.
