As the only child in an upper-middle class family, Rowan has had it easy. Doted on by a mother who never wanted anything but a child to love, she's never wanted for anything. Kiaya’s life, however, has been anything but easy. Parents who didn’t want her, followed by being torn away from her only sibling by the foster care system, she knows what it means to have to work hard for the things she wants. When a deadly virus sweeps the country, Rowan and Kiaya are away at college and far from everything they love.

From the moment Andra hears about the mysterious illness spreading the globe, she knows it’s the end. Sheltering in place with her daughter, ex, and his new family, they watch in dread as the world begins to crumble around them, while rumors of survivors turning into monsters spread. When the dust finally settles, all Andra wants to do is keep her daughter safe as they build a new life for themselves. But a fresh horror awaits, and it’s going to take all of them working together to survive the new world they’re facing. And maybe not even then....

Twenty years ago a deadly virus swept the globe, ravaging the population. People died and came back as monsters, and through the tragedy that rocked the world, survivors were born.

Rose Winter has enough problems. With a marriage going down the tubes and a dreaded anniversary party on the horizon, the last thing she needs is the zombie apocalypse. She wanted to get drunk and sing karaoke, not murder her undead neighbors. It’s clear the party’s over, however, now Rose has more problems - a missing husband, an overbearing houseguest, and keeping her family alive.

Cassie Forrest isn't surprised to learn that the day she’s decided to get her life together is also the day the world ends. After all, she’s been on a self-imposed losing streak since her survivalist parents died: she’s stopped painting, broken off her engagement to Adrian and dated a real jerk. Rectifying her mistakes has to wait, however, because Cassie and her friends have just enough time to escape Brooklyn for her parents’ cabin before Bornavirus LX turns them into zombies, too.
