A deadly and unprecedented virus is spreading. But those who survive it experience long-term effects no one has ever seen before: utter contentment. Soon after infection, people find the stress, depression, greed, and other negative feelings that used to weigh them down are gone. More and more people begin to revel in the mass unburdening. But not everyone. People in power—who depend on malcontents and prey on the insecure to sell their products, and convince others they need more, new, faster, better everything—know this new state of being is bad for business.

Joni Lark is living the dream. She’s one of the most coveted songwriters in LA…and she can’t seem to write. There’s an emptiness inside her, and nothing seems to fill it. When she returns to her hometown of Vienna Shores, North Carolina, she hopes that the sand, the surf, and the concerts at The Revelry, her family’s music venue, will spark her inspiration. But when she gets there, nothing is how she left it. Her best friend is avoiding her, her mother’s memories are fading fast, and The Revelry is closing.

Fifteen-year-old Marisol is the daughter of a soucouyant. Every new moon, she sheds her skin like the many women before her, shifting into a fireball witch who must fly into the night and slowly sip from the lives of others to sustain her own. But Brooklyn is no place for fireball witches with all its bright lights, shut windows, and bolt-locked doors.… While Marisol hoped they would leave their old traditions behind when they emigrated from the islands, she knows this will never happen while she remains ensnared by the one person who keeps her chained to her magical past—her mother.

Jane Vandermaker-Cook would like her mother back. As Jane's mother tours the world to support the family, Jane lives and goes to school in a Victorian mansion with her younger brother and their mendacious father who confines Jane’s mother to a system of pneumatic tubes whenever she’s at home. And then there's weirdly ever-present Aunt Finch, Milorad the gardener, and his rat, Brutus. For Jane, this all seems normal until she suddenly gains access to the files for a lifetime of security-camera videos—her lifetime.

Since Shelbi enrolled at Windward Academy as a senior and won’t be there very long, she hasn’t bothered making friends. What her classmates don’t know about her can’t be used to hurt her—you know, like it did at her last school. Andy Criddle’s had far too much to drink. Again. Which is bad. And things are about to get worse. When Shelbi sees Andy at his lowest, she can relate. So she doesn’t resist reaching out. And there’s no doubt their connection has them both seeing stars . . . but the closer they get, the more the past threatens to pull their universes apart.
